Program for chipboard cutting chart. Availability of libraries of double-walled fittings. Use of business waste

Cutting chart - is a documentation that displays which parts need to be cut from a chipboard sheet. But, in fact, it is possible not only to cut chipboard, but also any sheet material.

With the help of nesting, you can see how you can lay out the parts on the sheet. The map also contains information about the remains that will be as a result of cutting.

In the end, the advantage of cutting is to display the amount of material that will be required to create furniture.

You can also cut chipboard in the company where you will buy materials, but our task is to create cabinet furniture at home with minimization of costs, and it will not be difficult to make it yourself, even for a beginner.

To create a map, we will use the Cutting 2 program (cutting). You can download it for free at the end of the lesson.

The program interface looks like this:

In the "Materials" field, you must specify the parameters of the chipboard sheet, or, if you have leftovers that you plan to cut, then the size of the leftovers. As for chipboard size, I use Swisspan sheets, whose dimensions are 2750 * 1830 mm (for large sheets) and 2440 * 1830 mm (for small ones).

Also note that in the settings of the chipboard sheet, it is necessary to set the values ​​\u200b\u200bof “Sheet cut”, since the sheets initially have chips.

If you plan to glue the PVC edge, or if you want to calculate how much paper edge is required for gluing, then you can also set it in the "Properties".

Hello, friends.

In this article, we will talk about one practical side of making furniture.

Having designed any furniture, you get its detailing, or a list of all the parts necessary for its assembly.

And the next step will be the purchase of chipboard sheets, and cut them into these very parts you designed.

Here you can have two options:

Either you carry your detailing to where you will have chipboard (and, this is basically the same place where you will buy it), and they will do it according to your detailing, cut sheets of material into the necessary parts.

Or you will initially make a scheme according to which the sheet material will be processed.

Cutting cards - and there is that scheme for cutting a sheet (for example, the same chipboard) into the necessary parts.

Any such map always shows the presence of residues of the material used.

The same parts can be laid out on a sheet so that in one case, the size of the residues will be large, and in the other case, smaller.

Of course, large leftovers are always needed, since they can still do something.

Therefore, in the case when someone makes this documentation for you, then the size of your balances depends only on him.

And if you do it yourself, then you arrange the parts in such a way as to get the largest possible leftovers.

Of course, no one does it manually, as it is very laborious.

For these purposes, very good programs have long been invented.

But, we will consider a simpler option: One original chipboard sheet, and detailing for it.

Before calculating the details, in the original sheet, you can set the cut along the ends (in this case, 7 millimeters each).

After that, by clicking on the "calculator" icon, the program will automatically arrange the details according to the specified sheet.

As you can see in the figure, even if some details did not fit into the sheet, they can be seen in the window below.

In this window, the location of any parts can be changed at your discretion, rotate them around the axis (unless, of course, in the properties specified in the settings of the parts, this function is not blocked). In a word, do everything to get the largest possible balances.

When the details are laid out as needed, you can click on the view of this sheet.

In this mode, the layout of all parts is shown, the total length of the cut, the areas of parts and residues, in a word, all the necessary information.

After that, by clicking on the corresponding icon, all sheets with cutting, as well as a list of all parts, can be printed on the printer.

This will be your cutting map (furniture edge gluing is also marked on it, and sketches of non-standard (curvilinear, etc.) parts).

Thus, as you can see, it is quite easy to make the sheet cutting pattern yourself.

I think that the most ordinary furniture maker should be able to do this, since all this, in a sense, speaks of the level of his qualifications.

Well, on this I will “round off”, see you soon.

This article is the logical conclusion of a series of articles on independent design and calculation of furniture for the home.

Here I will talk about how to make economical cutting at home, point out all sorts of nuances and possible pitfalls that you should be prepared for when deciding to order chipboard cutting in furniture production.

FAQ or Frequently Asked Questions

1 - Why do the cutting yourself?- First of all, independent cutting of parts in a chipboard sheet is your savings.

The fact is that most furniture companies that cut chipboard sell boards by the piece. That is, if the parts you need do not fit on a chipboard sheet, and at least one piece ends up on the second plate, you have to pay for two full sheets of chipboard.

Agree, it is not very profitable to pay for two plates, if in fact it turns out that only a sheet of chipboard and a couple of small details go to the closet or kitchen.

That is why, it is better to make a cut yourself at home, according to which you can order a cut in a furniture workshop.

2 - What should I do if, anyway, after cutting the chipboard, a large residue is obtained?- It's simple - take a fresh look at your apartment and house. You may need a small coffee table or bookshelves.

Use the rest wisely, think of some new decorative and functional elements for the interior and add them to your nesting.

Thus, the purchase of chipboard parts will turn from obviously unprofitable into very economical and thoughtful.

3 - What is the structure of chipboard? How to understand the expression of furniture makers - according to the structure or against the structure?- Pay attention to the coloring of laminated chipboard, if there is a tree-like pattern in it, then it has a schematic representation of this very “structure”, namely, the structure of the tree bark, imitating a particular species (beech, ash, pine, oak, alder, cherry and others.)

Agree, furniture facades look rather silly, on which the pattern (structure) is scattered - on one along, on the second across, then again along.

Therefore, before ordering chipboard in production, you must have on hand a list of parts written according to certain rules and sequence.

So, pay attention to how the laminated chipboard with a pattern looks like.

We see that the structure goes along the long side. And, if the details lie parallel to the depicted fibers, furniture makers will call such a detail “according to the structure”, but if it is perpendicular, then “against the structure”.

4 - How to correctly specify the dimensions in the list so that parts of the same type have the same structure pattern?- The first and most important thing is to determine the visible elements on which the structure must be located in the same direction.

For example, facades, cabinet sides, front plinth. But those parts that are located inside the cabinet (internal shelves, sides of drawers and the like) can be cut randomly from a chipboard sheet.

When specifying the dimensions for the furniture workshop, it is better to clarify in advance where you plan to cut the laminated chipboard, which size of the part to indicate first.

In most furniture companies, the size of the part that goes along the structure, that is, along the pattern, is the first to indicate the size of the part.

And now carefully review the schematic sketch below - on it I tried to depict as clearly as possible how the details will look with the sizes indicated by the structure and against the structure.

5 - What is the basing of a chipboard sheet? Why, when cutting chipboard parts on your own, indicate the size of the plate less than the actual one? - Indeed, knowing the standard dimensions of a laminated chipboard sheet, when creating a cutting, you need to take into account the basing of the sheet, which will definitely be done in the workshop before cutting the parts.

Usually, the edges of the slab contain some chips, bumps, perhaps even a slight swelling. Therefore, sawmills "base chipboard sheet" - cut 10-15 mm on each side. Based on this, you must also make a base, that is, take it as the correct size, for example, not 1830 x 2750 mm, but 1810 x 2730 mm.

6 - What is the width of the cut and what is it equal to?- The kerf width is the cutting width of the saw. The saw installed on the sawing machine has a thickness of 4 mm, which means that between the parts there will be a cut with a thickness of these same 4 mm.

That is, the actual size on which two parts 300 and 400 mm will be located is not 700 mm, but 300 + 400 + 4 = 704 mm. Each cut must also be taken into account when cutting.

Well, that's all, now you are prepared to proceed directly to independent cutting of chipboard parts, which can be done in two ways - manually, using a ruler, leaflet, eraser, calculator and using a computer offline or online cutting program.

Manual cutting of chipboard parts: Step by step instructions

1 Draw on a sheet of paper, preferably on a scale, the dimensions of the plate. Remember to reduce it on each side by 10 mm.

2 Sort the list by the same type of required parts. For example, the sides of kitchen cabinets have the same dimensions - 500 x 712 mm.

There are quite a few of them, write out all such details separately. By the same principle, you continue sorting: the same width, the same structure, and so on.

3 Lay out on a sheet of chipboard first large parts and those that should have a similar structure. Don't forget about the saw blade width - 4 mm! This is where a calculator comes in handy.

4 Place the rest of the details. You can work out several options until you get the one that is ideal, as economical and profitable as possible.

Cutting details in a chipboard sheet using computer online and offline programs

On the Internet, in the public domain, there are many chipboard cutting programs that offer several cutting options at once.

Such programs can be searched for on specialized furniture forums or simply by typing into any search engine the query: “Chartboard cutting program for free.”

The search will return three main options:

1 Download the cutting program to your computer - the most common and most convenient for beginners cutting program for chipboard - Cutting. Simple interface, clear layout and many options for sawing the sheet.

2 Create chipboard cutting online - here you don’t need to load your PC with programs that may not be useful in the future.

3 Cutting and ordering chipboard sawing online on the website of a furniture company is an ideal option if the production workshop is geographically convenient for you.

Thus, you will "kill two, or maybe more, birds with one stone" - select chipboard on the website, which is available in the required quantity, make an economical cut, see the cost and immediately, sitting at home, order a chipboard cut in a furniture workshop.

I'll reiterate the important points...

Basic rules for cutting chipboard

• The size of the laminated chipboard sheet must be entered taking into account the basing of the plate.
• The cutting width of the saw is 4 mm.
• Details in the cutting must be made taking into account the structure.

If you have any questions - ask them right here, under the article. I'll try to answer promptly.

Also, if there are current furniture topics that you would like to read about, write about them in the comments. Perhaps this is what will serve as an impetus for writing the next article.

Always yours, Timur Denisov.

Cutting 6.54.121 is an interesting and necessary program with the ability to build a cutting map for various industrial materials. For example, cutting chipboard, glass, plastic, roll materials and sheets.

The main "chips" of the program:

• Work begins in the application with the introduction of the concept of "Order". It is considered that this is a complex of parts with specified parameters of height and width. Details are set in a rectangular shape.
• You can specify the desired number of parts in the order. In this case, the program will give the optimal number of sheets to be purchased.
• It is possible to view the history of orders, change an already completed one, or repeat it with new parameters.
• For each individual element, it is possible to set a symbolic name, the number of these elements and the presence / absence of an edge (in particular, in the production of furniture panels).
• Along with standard sheets, it is possible to enter additional sheets and cut them next to the main ones.
• You can specify the amount of "business waste" for their subsequent use. This is possible under the condition of large, mass production.
• You can specify the amount of technological waste, for example, the consumption of material for sawing.
• When conducting settlement, it is possible to combine different orders from the same material. Thus, you can save on cutting.
• In the free cutting program, you can work with two types of edges.
• The cut is made by the guillotine method, that is, from edge to edge. All cuts are even, strictly vertical or horizontal.
• There are two ways to nest in the software: minimizing waste (maximum material utilization) and maximizing continuous trim (minimum waste plus maximum business trim).
• When cutting material in a roll, the program on the machine is able to choose the option for placing elements on the tape. All parts will be rectangular and of unknown height.
• It is possible to use the cutting program in network mode.
• There is no language barrier, as the program has been released in Russian.
• The interface is simple, in soothing colors, like any other graphics program.
• Operating systems for which the program is suitable: WindowsXP, WindowsVista, Windows7.

The program for cutting sheet and roll material is used in various technical and industrial productions, plants, factories, as well as in small enterprises. In domestic conditions, with the help of this program, you can make calculations for the construction of a garden or a bath, repairing an interior or facing a house. Cutting 6.54.121 will provide high-quality and fast calculation of the material. Most often, the application is used to calculate chipboard and glass.

First I used Cutting 2, then Cutting 3. They differ quite strongly. But I liked the Cutting 2 version better. The third version has additional features that, by and large, are not really needed for small-scale production. Cutting 2 still helps me to pre-calculate the amount of material and the length of the cut lines for large orders, such as the kitchen. To create the final cutting map, I use the Nowy Rozkrój program (Cut Optimiser or New Cut Manager) from the creators of the PRO100 program. . Both sites can be switched to Russian and read the description of the programs. And now I will describe the simple process of creating cutting maps. .

We open any project created by us in PRO100. Click on the Σ tab.

In the window that opens, a table will be displayed in which all elements of the project with their characteristics will be indicated. At the bottom of the window we find the Copy All tab.

We click on it. Now we can insert a table with our elements into the parts list in Cutting 2. But we only need elements of the base material, let's say 18 mm chipboard. Therefore, we open Excel and insert a list of PRO100 elements. Now select those lines in which the elements are not 18 mm and delete them. As a result, there remains a table consisting of 4 columns, in one of which there is only the number 18 in all cells. Select and delete this column. The remaining elements are selected and copied. We launch the Cutting 2 program. The parts table is on the right.

If it is not empty, click on the X icon above the right table and confirm clearing the list. Now we right-click on the first empty cell of the list and select the line Add from clipboard in the drop-down menu.

Click on the Execute Calculation icon.

The cutting map is ready. Can be printed and used. But I ran into some inconvenience. For example, the numbers are small, the cut lines are not clear enough.

The people who cut the material for me were unhappy with the need to use a magnifying glass. But for the preliminary calculation of the cost of the product, the program was ideal due to the transfer of parts from PRO100 to Cutting 2 described above.

Nowy Rozkroj's program is a better optimizer.

However, all part dimensions must be entered manually.

The program calculates several cutting options at once.

Depending on what is important to you, you choose your option. The option with a smaller total length of cut lines is more suitable for me, but someone needs an option with fewer trimmings (trash).

First, in the settings, I specify the cutting option without a strip,

which allows you to place more parts. After the first attempt at cutting, I see how much free space remains on the last sheet. If more than 30% is not occupied by details, then in the program parameters I indicate the horizontal cut option

and run the final calculation. The seller keeps the remaining horizontal stripe of the popular colors of the material, which reduces the cost of furniture. The nesting maps created by Nowy Rozkroj are detailed and clear enough, and the dimensions are displayed perfectly.

Cutting result may be different. For example, you made the optimal cutting with the option without a strip, and you got 3 sheets and 3 parts. This is especially important if the seller does not sell this color of the material in a strip, but only in a sheet. In this case, apply the following option:

When adding each part, uncheck the box in the Part properties table in the Structure position.

Then, looking at your project, go through the detailing and note the structure in the details, the structure on which can only be consistent with the design, i.e. other variations of the structure on these parts are not acceptable. If this method does not help, then reduce the dimensions of hidden parts, such as plinths and connecting strips, by 10 mm or more. But don't overdo it.

There is another important advantage of this program. If you marked an edge on one side of a part, it will not move from that side to the other when the part is rotated by the optimizer, which can happen in other programs. In the event that the end edge is paper, the dimensions of the parts remain the same as in the project, and if the PVC edge is 1-2 mm thick, then do not forget to subtract the thickness of the edge from the size of the adjacent side with the glued edge.

An example of nesting maps

At the beginning of the video, until the start of the Nowy Rozkrój program, do not pay attention. And then everything on the topic. A small technical hiccup.

If your sheet is, for example, 2800 by 2070, and the cut along the side is 10 mm, forgetting that 4 mm is needed for the cut, you indicate the size of the part 2790 by 600 with an edge of 2790. As a result, the edge slips by 600. Pay attention to it's attention. I once did not check the card and gave it to work. Firstly, the guys suffered when they glued the edge on the 600 side, because. the part rested against the door of the workshop, I had to move the machine. No one thought that the distance from the machine to the wall of 2.5 m could ever be insufficient. And secondly, I had to pay for the edge to be glued on the long side, and at that moment I did not count on it. Therefore, be careful.

Cutting - a program for cutting sheet materials: chipboard, glass, etc. The chipboard cutting program allows you to reduce and optimize material consumption, it keeps track of waste, including “business” waste, which is not taken into account when calculating the cost of an order. The utility can be used at enterprises engaged in the mass production of cabinet furniture; for this, the concept of an order has been introduced into its functionality. All completed orders are automatically entered into the database of orders, subsequently it is possible to repeat or change them. You can download it for free on this website.

To start working with the utility, you need to set the dimensions of the sheet and the parts that will be cut from it. Further, the program will independently select the best cutting option with the least amount of waste. If necessary, you can use the database of materials available in the program, which contains the standard sizes of sheets or rolls. In this case, it is enough to specify the material for cutting, and the utility will automatically calculate according to the standard parameters of the sheet.

The cutting program works according to two main algorithms for optimizing chipboard consumption - reducing the total waste and increasing continuous trimming. Reducing overall waste means cutting with a minimum number of scraps. The continuous cut increase mode, in addition to reducing waste, is used to create a maximum cut, which can then be used for another order. You can also save material costs by combining two orders if they use the same material.

The main advantages of the Nesting utility

• Two cutting optimization algorithms.
• Database of standard sheet sizes.
• Work with two types of edges.
• Works with both sheets and rolls.
• Database of executed orders.

During cutting, all cuts are made from one edge of the sheet to the other - either horizontally or vertically. The material consumed for sawing and other technological operations is taken into account when calculating the cutting. The utility allows you to work with two types of edges. The program allows you to optimize the consumption of not only sheets, but also rolls. If necessary, it is possible to use Nesting in network mode.

Optimization of the cutting of various sheet materials is carried out in special programs, which helps to do everything right and save a lot of time on this task. We have compiled a small list in which we have selected for you several representatives of such software.

"Master 2" provides users with great opportunities not only in drawing up a cutting project, but also in doing business. Multi-user mode is supported, sorting and systematization of the entered information is present, data on materials and contractors are saved.

The implementation of the warehouse will help to always be aware of the remaining amount of materials. There is a distribution into tables where active orders, scheduled and archive are located, all information is available to the administrator for viewing and editing. "Master 2" has several assemblies, one of them is distributed free of charge and is available for download on the official website.

Cutting 3

This representative with a huge selection of materials and parts is more suitable for individual use. The cutting is well optimized, the user only needs to enter the required dimensions, select materials and specify additional settings, if necessary.

Cutting 3 gives users the ability to use files from other programs, such as loading parts from . In addition, visual design is supported.

Astra Cutting

"Astra Cutting" simplifies the cutting process as much as possible. All you have to do is load the parts, specify their dimensions and wait for the nesting plan to be processed. Third-party and official libraries of furniture and other objects are supported that are suitable for harvesting in this way.

We recommend that you pay attention to the presence of built-in documentation. It is systematized and formed in the course of work on the project. Just go to the appropriate tab when you need it and print any of the prepared documents.

There are many programs on the Internet that perform the same actions as the representatives of our article, but they all copy each other. We have tried to select the most suitable and high-quality software.

The program is designed for a comprehensive solution of the problems of cutting sheet materials. It combines the capabilities of the system for preparing control programs with the functions of organizing the production process. The approach to the solution used in the program summarizes the experience of a number of enterprises operating thermal cutting machines.

Database usage

The program integrates traditional Techtran processing software with a database. The database is entrusted not only with the task of managing various data, but also with managing the operation of the system as a whole, since the database objects are also sheet cutting programs. First of all, details are entered into the database, which can be imported from another system, built using Techtran tools or created on the basis of macros.

Creating Macro-Based Parts

In the course of working with the program in production conditions, a number of typical parts are gradually distinguished, differing in size and the presence or absence of some auxiliary elements. It is convenient to store such typical parts in the library in a parameterized form and use them when creating real parts by setting the actual parameter values. The program allows you to use parameterized parts when creating a part in the database. Detail parameters are entered in the dialog box. Users have the opportunity to develop macros that describe the geometry and, if necessary, the processing of typical parts. It is also possible to define parameter descriptions to customize the dialog box and control input.

Correction of incorrect geometry when importing DXF files.

The system implements the ability to adjust the accuracy of conjugation of contours when importing DXF files. Pairing accuracy is the distance within which the mismatch of the original segments is allowed, which is eliminated when they are converted into contours. The accuracy of the pairing affects whether closely spaced segments will be combined into one contour or not. If the boundary points of the segments do not match, but the distance between them is within the accuracy of mating, such segments are mated (combined into a single contour). Segments are mated due to their continuation, truncation or displacement of end points - depending on the relative position of the segments:

a) Truncation of segments.

b) Segment extension.

c) Segment Offset "Short" segments (having a length less than the matching accuracy) are eliminated.

After removing the "short" segment, adjacent segments are paired. Segments (or parts of segments) that overlap within the mating accuracy are merged. Details are conveniently viewed simultaneously with a list of all details. To manage parts and other database objects in Techtran, a single visual mechanism is offered using two panels. This approach allows you to perform actions on database objects from the list (create, delete, edit and view parameters) and at the same time see a graphical representation of the list elements (parts, sheets, sheet layouts, etc.) on the adjacent panel. In addition, the presence of two panels makes it convenient to work with objects that include other objects in turn. So, for example, a sheet nest contains details. To organize the viewing of parts related to different sheet layouts, one panel can display a list of sheet layouts, and the other - a list of parts placed on a specific sheet.

Cutting task

The program organizes the interaction of various objects involved in the process of cutting sheet material. From the parts that need to be made, a cutting task is formed. Then, sheets for the manufacture of parts are included in the cutting task. The program provides the possibility of automatic and manual placement of job details for nesting on sheets. At the same time, the program monitors the number of unplaced parts and the possibility of manufacturing a part from the selected sheet.

Automatic placement of parts on a sheet

In the automatic nesting mode, the program stacks the details of the job on the sheets in an optimal way. Required additional sheets can be automatically taken from the warehouse. The program also allows you to automatically place selected parts on a specific sheet. At the same time, the specified distances to the edge of the sheet and between the parts are maintained. The automatic nesting strategy provides a very high material utilization. The user has the opportunity to choose the optimal ratio between the quality of placement of parts and the calculation time. Automatic nesting sets how parts are compacted on a sheet that is not completely filled. This affects the form and proportions of business waste, taking into account the specifics of its further use. Controlling the selection of parts for filling holes allows you to use smaller or larger parts to place in voids inside parts, or not to fill holes at all.

Manual placement of parts on a sheet

There is a manual mode for placing parts on a sheet. In this mode, a part is selected from the list of unplaced parts of a cutting task and placed on a sheet, and then moved to a free place using the graphics editor. There are also means of precise control of the relative position of objects. The combination of automatic and manual part placement makes it possible to take advantage of the advantages of each mode for the most efficient work.

Parts movement control

In the manual placement mode, the program takes on a number of useful functions. These include various ways to move parts while maintaining the required distances between parts and between parts and the edge of the sheet, as well as the ability to place parts close to each other.

Strict control of the movement of parts. Enabling this function allows you to move parts around the sheet on the monitor screen, like real objects, for which other parts and the edge of the sheet are an insurmountable obstacle.

Predictive control of the movement of parts. With preventive control, the movement of parts is not limited to the free area of ​​the sheet. However, when it enters the overlap zone with other objects, an invalid location is diagnosed by changing the color of the part being moved.

Moving parts to the stop. This function makes it possible to press the part close to the very edge of the free area of ​​the sheet. In other words, during this operation, the part moves in a certain direction until it rests against the part or the edge of the sheet.

Copying parts close to each other.

When copying parts in this mode, the distance that the part can be moved in the specified direction is automatically determined so that the parts are located close to each other.

Combining the sides of the parts allows you to orient the parts in such a way as to combine them with the selected sides.

Align parts in a straight line. This feature is useful when arranging parts for through-cut processing.

Processing programming

After the parts are placed on the sheet, processing is programmed. In the simplest case, it is sufficient to sequentially indicate the contours of the parts to be machined. The program builds the trajectory of the tool movement, taking into account the necessary corrections, generates approaches, withdrawals and auxiliary movements of the tool, commands to turn the cutter on and off, feed, correction, etc.

Approach and departure. It is possible to set various ways of approaching the contour being processed (along a straight line, along an arc, along a normal, along a tangent, etc.), selecting an approach point (automatically or explicitly) and operating modes of the cutter at various stages of processing.

Jumpers. On the contour of the part, impervious sections - jumpers can be highlighted. When constructing a trajectory, the program automatically generates cutter on and off commands in such places and embeds approach and departure sections.

bridges between parts allow you to process multiple parts without turning off the torch. Setting the transition points of the trajectory from one part to another is done after placing the parts and is taken into account when constructing the final cutter trajectory.

loops provide high-quality processing of corners of parts and can be assigned to any corner.

Assigned processing. To simplify the work, the processing of parts can be programmed at a preliminary stage so as not to repeat the same actions to repeatedly include elements in the nest.

Manual processing Yu. For non-standard cases, it is possible to construct a trajectory and set technological commands in an explicit form.

subroutines provide structuring of the resulting control program and reduce the volume of the generated text.

Processing parts with a combined cut. Pairs of parts placed on the sheet at a distance of the cut width can be processed in a single cut without turning off the cutter. When machining individual parts, it is enough to specify the contour of the part that will be machined first.

Pre punching. When processing thick sheets, it may be necessary to punch holes in the sheet first and then perform the main processing. Either a separate cutter or a drill can be used for this pre-treatment of the sheet. The program allows you to perform processing with pre-punching holes. It is possible to set various pre-piercing methods.

Positioning over the material. In some cases, when moving from contour to contour, it is necessary to move the cutter, bypassing parts and waste separated from the sheet. This function is necessary when cutting foam rubber. It is sometimes required in thermal cutting to prevent the torch from colliding with cut parts and scrap. The program provides the possibility of such positioning, taking into account the specified distance to the part and to the edge of the sheet.

Automatic processing

The automatic processing mode makes it possible to simplify the programming of processing a large number of parts as much as possible. The program itself assigns the sequence of bypassing parts on the sheet and performs processing. Various part avoidance strategies ensure that the required machining conditions are met.

Cutting edges for welding

Cutting edges for welding can be carried out on thermal cutting machines equipped with three-torch blocks. The program provides the possibility of processing parts with both constant and variable chamfers. A constant chamfer is characterized by the constancy of the front and rear angles and heights along the entire length. A variable chamfer is characterized by a uniform change in angle and height along the length. The program automatically embeds special sections in the cutter's trajectory - incision windows in the places where the side cutters are turned on and the cutter reversal loops, which ensure the correct orientation of the side cutters and compliance with the necessary processing conditions. The position of the entry windows can be changed using the graphical editor.

Sheet layout

Marking on the sheet can be done using powder or core. Stakeout outlines can be stored in the database along with the part. In this case, the markup is placed on the sheet along with the details. To program the operation of the marking block, it is enough to specify the marking contours in the desired sequence. The program will make all the necessary switching and build a trajectory.

Multi-Support Machining

On machines equipped with multiple calipers, multiple parts can be cut at the same time. The program provides automatic and manual placement of parts, taking into account the capabilities of such equipment. When programming the processing, the required wiring of the calipers is carried out automatically.

Use of business waste

From the unused part of the sheet, business waste is formed, which can be placed in a database for later use.

Documentation

The program generates the following output documents:

• sheet cutting chart
• sheet cutting specification
• cutting job specification.

As a rule, the specific type of output documents is determined by the traditions of the enterprise. The report generator included in Techtran has a flexible mechanism for customizing the format of documents and the amount of output information.

Automatic text generation

In the process of constructing geometric objects and designing sheet cutting, the text of the program is formed in the Tekhtran language. The program includes the entire sequence of actions performed and can be used in further work. This allows you to flexibly combine the convenience of the dialog mode with the advantages of the textual representation of the program, which include:

• Use of previously written programs and macros, their quick modification
• Parameterization for generic parts
• Using conditional statements, loops, arithmetic expressions, and functions
• Ability to debug and fix errors

Tools for developing and debugging programs

The system includes a set of tools for working with the program in the Tekhtran language:

Execution Commands(execute a statement, go to a macro, run the program to the end, to the cursor, etc.) allow you to execute and debug the program in Tekhtran. Using these commands, you can execute the program as a whole or in parts, pausing the process to analyze the results of the execution of individual statements.

Execution controls make it possible to view the values ​​of variables, use the graphical window for visual control of program objects, and view diagnostic information generated during program execution.

Getting the control program

The postprocessor, which is part of Techtran, allows you to generate control programs for various CNC machines according to the part processing program and equipment data included in the system. Using a part program obtained for one machine, it is possible to obtain a NC for any other machine from the equipment list.

Customization for specific CNC equipment

Techtran provides the ability to customize to specific CNC equipment. To describe the equipment, you need to fill out the machine passport and create a machine module in a special language Techpost. Such a mechanism allows users to independently take into account the features of the formation of UE, developing their own modules based on existing ones.

Version 7 features:

The automatic placement mode using the hodograph allows you to:

• Place parts on sheets and free-form business waste
• Place parts additionally on sheets that already have parts on them, increasing material utilization

Processing check

• Control of overcutting of parts during processing
• Out-of-sheet toolpath monitoring
• Checking for Unfinished Parts

Advanced mechanism for automatic generation of business waste contours

Increasing the number of contours when generating business waste in automatic mode

Combining Adjacent Pieces of Business Waste Sheets

batch processing

Batch processing has been implemented - a mode of operation in which a number of actions are automatically performed on sheet layouts. The task of batch processing is to perform a sequence of lengthy operations, save the user from repeatedly opening database objects, thereby reducing the amount of routine work and increasing efficiency.

In batch processing mode, the following actions can be performed:

• checking the correct position of the parts on the sheet
• automatic processing of parts
• checking the received trajectory for gouges
• obtaining contours of business waste, nesting maps, control programs, processing statistics, sheet nesting specifications
• export of parts and toolpaths

Calculation of the cost of cutting parts

The calculation allows you to determine the cost of work for the reporting period. The report forms the cost of cutting, calculated on the basis of special tables filled in by the user. Calculation formulas can be adapted. The solution cost assessment takes into account:

• the cost of cut sheets;
• the cost of business waste;
• scrap value;
• slag cost;
• cost based on:
• total processing time (includes equipment depreciation and staff salaries);
• number of punches (includes consumption of nozzles, gases, energy);
• cutting path/time (includes consumption of nozzles, gases, energy).
• path / time of idling (includes the consumption of gases, energy).

The cost is calculated separately for each sheet cutting.

Costs can be summed up for a cutting job specification.

The cost can be distributed among the parts in proportion to their area and perimeter.

Calculation formulas can be adapted individually to the specific requirements of the enterprise.

Duct Library

A library of air duct elements has been developed, consisting of shaped parts of air ducts (optional).

Using the library allows you to:

• receive part developments with the required characteristics
• using the preview window, select the optimal combination of those parameters that are not fixed (for example, the location of the cut line of a cylindrical section).
• include additional connecting elements in the detail - folds.
• take into account the thickness of the sheet in order to compensate for the deformations of its outer and inner surfaces that occur during the bending process.
• if necessary, split the part into several fragments
• select elements and assign geometric and technological parameters in a dialog mode
• automatically generate sweeps taking into account the bend radius
• quickly view and change deployment options
• view 3D models of resulting joints

Using the library of duct elements will allow you to:

• reduce reaming design time
• take into account the technological features of the connections of elements
• get high accuracy of sweep construction
• control the geometry of the constructed sweeps at the design stage

Importing dstv (nc) files

Import will allow you to transfer not only the geometry of parts and its designation, but also the number of parts required for nesting, indicating the thickness of the material. Programs supporting DSTV(NC) format - Tekla Structures, Advance Steel, StruCAD.

Automated production system PractiCAM™ is focused on the production of products for ventilation systems from sheet and rolled metal, as well as from pipe blanks. PractiCAM™ works with plasma and laser machines with numerical control (CNC), as well as with stamping, spiral and coordinate punching machines. The program has great functionality for cutting sheet metal, i.e. it is focused not only on the production of air ducts, but also flat parts, signboards, weather vanes, roof elements, etc.

The main advantages of the PractiCAM™ system:

	Creation of air ducts of any type, as well as any other elements from sheet and rolled metal, and pipe blanks
	System Libraries PractiCAM™ very extensive and unparalleled. They contain over 4000 fittings and over 1600 parameterized flat parts. Despite this diversity, the system libraries PractiCAM™ are still increasing (every time you download a new version of our program, new items will be waiting for you). In addition to existing libraries, we can create as many different fittings, flat parts and other elements for you as you wish. We will make the parts you need and send them to you as soon as possible (as a rule, the development of a new part, depending on its complexity, takes from one to three working days).
	Compatible with any equipment
	System PractiCAM™ supports many models of plasma and laser CNC machines. It can also work with punch, scroll, jig punches, pipe cutters and bar code readers. If your machine model is not yet in our library, then we will write a postprocessor for you free of charge in the shortest possible time, which will connect our program with your equipment.
	Instant and accurate cost estimates
	During your work, the system PractiCAM™ continuously creates an accurate estimate of the cost of all costs for the manufacture of parts. The full calculation takes into account the cost of the material, labor costs for the manufacture of parts, the cost of all fasteners (bolts, screws, tires, rivets, etc.), as well as the cost of various accessories (blades, rods, dampers, etc.). As an example, the American SMACNA tables are given, but you can create your own standard tables for accounting for labor costs in your enterprise, taking into account the specifics of your production.
	Export and import of information in common .dxf, dwg and .csv formats for communication with software products of 1C, Microsoft, Autodesk companies
	All information about the spent metal, consumables and components contained in the system Practicam™, can be converted to a .csv file, which is supported by 1C: Accounting and Microsoft Excel. This makes it possible to calculate the cost of all your products using accounting programs. System PractiCAM™ can work with .dxf and .dwg files, which allows you to import drawings from AutoCAD and Compass programs, as well as export nesting plans, fitting patterns and flat parts to these programs.
	Import orders from the program 1C: Accounting
	In the 1C: Accounting program, you can create orders for cutting fittings, indicating the names of fittings, their quantity, the material from which they should be made, technological parameters, names of allowances, etc., and send them to the system PractiCAM™. After receiving the order, the system PractiCAM™ automatically finds the specified fittings in its libraries, applies the specified parameters to them and lays out the fitting patterns on metal sheets. After automatic laying, control commands for your equipment are generated, as well as various reports and labels.
	metal saving
	It is possible to use the rest of the sheet metal, suitable for cutting out any products from them, and to maximize the use of the sheet area. To do this, the "Warehouse" functional module has been added, which allows, after laying the parts of the main work on metal sheets, to automatically add flat parts from a pre-created list to an unused place.
	Possibility of automatic stacking of products using a combined cut
	IN PractiCAM™ There are two options for automatic stacking of products: normal stacking and stacking with a combined cut for products that can be combined along one of the sides.
	Fully Russified
	In addition to the Russian language, the system PractiCAM™ translated into English, French, Spanish, Chinese and Korean.
	Various types of allowances
	Allowances (connectors, locks, joints, seams) and notches contained in a large number in the system libraries Practicam™, can be created in any geometric shape, fully parameterized and editable. The graphic editor provides ample opportunities for creating and editing allowances and notches.
	Report creation
	System PractiCAM™ provides you with a wide range of standard report templates. In addition to this, you can create your own reporting forms in any convenient format and with any type of layout. The main thing is that in the report you can report any information contained in the system Practicam™.
	Create labels
	Mark parts in the system PractiCAM™ easy and convenient. Various label templates are provided for your attention, but if they do not suit you, then you can create your own template. Add any information to your labels: your organization's logo, barcodes, 3D parts images, any part parameters you are interested in; edit these captions with any font style and size. You can make a label for any fitting and flat piece.
	Useful specifications
	Specifications (SNiPs) of the system PractiCAM™ allow you to set all the features of your production standards when working with different products, allowing you to unify production, automate the input of products for manufacturing and reduce input errors, thereby increasing your productivity, and with it your profit. You can create your own rules for the production of products that are used in your enterprise.
	Availability of libraries of double wall fittings
	In system PractiCAM™ there are libraries of double wall fittings. They are used in cases where it is necessary to increase the level of heat and noise insulation. For each double wall fitting, insulation can be cut to fit between its walls.
	Possibility of manual and automatic segmentation for large products
	System PractiCAM™ allows you to segment (break into separate components) large-sized products that do not fit on a sheet of metal. You can set the segmentation rules for each product yourself or entrust this process to the program.

Benefits of our technical support:

• Better product support — at the request of users, we develop and add new software modules, create new fittings and parametric flat parts (within 1-3 days, depending on the complexity of the product), add new ways of cutting fittings to existing ones.
• Free training to work with the program.
