Download the chipboard cutting program. Uncover
The program is designed for a comprehensive solution to problems of cutting sheet materials. It combines the capabilities of the control program preparation system with the functions of organizing the production process. The solution approach used in the program summarizes the experience of a number of enterprises operating thermal cutting machines.
Using the Database
The program combines traditional Tehtran processing programming tools with a database. The database is entrusted with not only the task of managing various data, but also managing the operation of the system as a whole, since the objects of the database are also sheet cutting programs. First of all, parts that can be imported from another system, built using Techtran tools, or created based on macros are entered into the database.
Creating Macro-Based Parts
While working with the program under production conditions, a number of typical parts are gradually identified, differing in size and the presence or absence of some auxiliary elements. It is convenient to store such typical parts in a library in a parameterized form and use them when creating real parts, specifying the actual values of the parameters. The program allows you to use parameterized parts when creating a part in the database. Part parameters are entered in a dialog box. Users have the opportunity to develop macros that describe the geometry and, if necessary, processing of typical parts. It is also possible to specify a description of the parameters for customizing the dialog box and controlling the input data.
Fixed incorrect geometry when importing DXF files.
The system has the ability to adjust the accuracy of contour matching when importing DXF files. Conjugation accuracy is the distance within which mismatch of the original segments is acceptable, which is eliminated when they are converted into contours. The accuracy of the mate influences whether closely spaced segments will be combined into one contour or not. If the boundary points of the segments do not coincide, but the distance between them is within the conjugation accuracy, 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) Extension of segments.
c) Displacement of segments “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 each other within the matching accuracy are merged. It is convenient to view parts simultaneously with a list of all parts. To manage parts and other database objects, Tehtran offers a single visual mechanism using two panels. This approach allows you to perform actions on database objects from the list (creating, deleting, editing and viewing parameters) and at the same time see a graphical representation of the list elements (parts, sheets, sheet cuttings, etc.) on the adjacent panel. In addition, the presence of two panels makes it convenient to work with objects that in turn include other objects. For example, the cutting of a sheet contains details. To organize the viewing of parts related to different sheet cuttings, you can display a list of sheet cuttings in one panel, and a list of parts placed on a specific sheet in the other.
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. The cutting job then includes sheets to make the parts. The program provides the ability to automatically and manually place parts of a cutting job on sheets. In this case, 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 automatic placement mode, the program places job details on sheets in the optimal way. Required additional sheets can be automatically taken from stock. The program also allows you to automatically place selected parts on a specific sheet. In this case, the specified distances to the edge of the sheet and between the parts are maintained. The automatic placement strategy ensures very high material utilization rates. The user has the opportunity to select the optimal balance between the quality of placement of parts and calculation time. Automatic placement specifies the method for compacting parts 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 to fill holes allows you to use smaller or larger parts to fill voids within parts, or not fill holes at all.
Manually placing parts on a sheet
There is a manual mode for placing parts on the sheet. In this mode, the part is selected from the list of unplaced parts of the cutting task and placed on the sheet, and then moved to free space using the graphic editor. There are also means for 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 manual placement mode, the program takes on a number of useful functions. These include different 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 parts movement. Enabling this function allows you to move parts across the sheet on the monitor screen, like real objects, for which other parts and the edge of the sheet are an insurmountable obstacle.
Preventive control of parts movement. With preventive control, the movement of parts is not limited to the free area of the sheet. However, when it enters an overlap zone with other objects, an unacceptable location is diagnosed by changing the color of the moving part.
Move parts until they 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 by which the part can be moved in a given direction is automatically determined so that the parts are located close to each other.
Combining the sides of parts allows you to orient the parts in such a way as to align them with the selected sides.
Aligning 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, the processing is programmed. In the simplest case, it is enough to sequentially indicate the contours of the parts to be processed. The program builds the trajectory of the tool, taking into account the necessary corrections, generates approaches, departures and auxiliary movements of the tool, commands for turning the cutter on and off, feed, correction, etc.
Approach and departure. It is possible to variously configure the methods of approaching the processed contour (straight line, arc, normal, tangent, etc.), selecting the approach point (automatically or explicitly) and operating modes of the cutter at various stages of processing.
Jumpers. On the contour of the part, non-cutable areas can be identified - jumpers. When constructing a trajectory, the program automatically generates commands to turn the cutter on and off in such places and builds in approach and departure sections.
Bridges between parts allows 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 trajectory of the cutter.
Loops provide high-quality processing of corners of parts and can be assigned to any angle.
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 cutting.
Manual processing Yu. For non-standard cases, it is possible to construct a trajectory and specify technological commands explicitly.
Subroutines provide structuring of the resulting control program and allow you to reduce the volume of generated text.
Processing parts using combined cutting. Pairs of parts placed on the sheet at a distance of the width of the cut can be processed with a single cut without turning off the cutter. When processing individual parts, it is enough to indicate the outline of the part that will be processed first.
Pre-punching. When processing thick sheets, it may be necessary to first punch a hole in the sheet and then perform the main processing. For such pre-processing of the sheet, either a separate cutter or a drill can be used. The program allows you to perform processing with preliminary hole punching. It is possible to specify various methods of preliminary punching.
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. Sometimes it is required during thermal cutting to prevent the torch from colliding with cut parts and waste. 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 a sequence for traversing parts on the sheet and performs processing. Various part bypass strategies ensure that the required processing conditions are met.
Cutting edges for welding
Cutting edges for welding can be done on thermal cutting machines equipped with three-cutting units. The program provides the ability to process 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 builds into the trajectory of the cutter special sections - cut-in windows in the places where the side cutters are turned on and cutter reversal loops, which ensure the correct orientation of the side cutters and compliance with the necessary processing conditions. The position of the inset windows can be changed using a graphic editor.
Sheet layout
Markings can be applied to a sheet using powder or a core. Marking outlines can be stored in the database along with the part. In this case, the markings are placed on the sheet along with the details. To program the operation of a marking block, it is enough to specify the marking contours in the required sequence. The program will make all the necessary switches and build a trajectory.
Multi-slide machining
On machines equipped with multiple slides, 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 processing, the required caliper layout is performed automatically.
Use of business waste
The unused part of the sheet generates business waste, which can be placed in a database for later use.
Documentation
The program generates the following output documents:
- sheet cutting map
- sheet cutting specification
- cutting task 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 document format and the amount of output information.
Automatic text generation
In the process of constructing geometric objects and designing sheet cutting, the program text is generated in the Tehtran language. The program includes the entire sequence of actions performed and can be used for further work. This allows you to flexibly combine the convenience of the dialog mode with the advantages of the text representation of the program, which include:
- Use of previously written programs and macros, their quick modification
- Parameterization for standard parts
- Using conditional statements, loops, arithmetic expressions and functions
- Ability to debug and fix errors
Program development and debugging tools
The system includes a set of tools for working with the program in the Tehtran language:
Execution commands(execute the statement, go to the macro, execute the program to the end, to the cursor, etc.) allow you to execute and debug the program on Techtran. Using these commands, you can execute the program entirely or in parts, pausing the process to analyze the results of executing individual statements.
Execution Controls make it possible to view the values of variables, use a graphical window for visual control of program objects, and view diagnostic information generated during program execution.
Obtaining the control program
The postprocessor, which is part of Techtran, allows you to create control programs for various CNC machines using the part processing program and equipment data included in the system. Using a part processing program obtained for one machine, you can obtain a program for any other machine from the list of equipment.
Customization for specific CNC equipment
Techtran provides the ability to configure specific CNC equipment. To describe the equipment, you need to fill out a machine passport and create a machine module in the special Technical Post language. This mechanism allows users to independently take into account the peculiarities of the formation of software programs, developing their own modules based on existing ones.
Features of version 7:

Batch Processing
Batch processing has been implemented - an operating mode in which a number of actions are automatically performed on sheet cuttings. The purpose of batch processing is to perform a sequence of time-consuming operations, saving 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 location of parts on the sheet
- automatic processing of parts
- checking the resulting trajectory for cuts
- obtaining waste contours, cutting cards, control programs, processing statistics, sheet cutting specifications
- export of parts and trajectories
Calculation of the cost of cutting parts
The calculation allows you to determine the cost of work for the reporting period. The report generates the cost of cutting, calculated on the basis of special tables filled in by the user. Calculation formulas can be adapted. When assessing the cost of a solution, we take into account:
- cost of cut sheets;
- cost of business waste;
- scrap cost;
- slag cost;
- cost calculated 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).
- idling distance/time (includes gas and energy consumption).
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 parts in proportion to their area and perimeter.
Calculation formulas can be individually adapted to the specific requirements of the enterprise.
Duct Element Library
A library of air duct elements has been developed, consisting of shaped parts of air ducts (supplied optionally).
|
|
Using the library allows you to:
- obtain parts scans 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 - folds - into the part.
- take into account the thickness of the sheet in order to compensate for the deformations of its external and internal surfaces that occur during the bending process.
- if necessary, split the part into several fragments
- select elements and assign geometric and technological parameters in dialog mode
- automatically generate development patterns taking into account the bend radius
- quickly view and change scan options
- view three-dimensional models of the resulting joints
Using a library of air duct elements will allow you to:
- reduce development time
- take into account the technological features of element connections
- obtain high precision in constructing scans
- control the geometry of the constructed developments at the design stage
Import dstv (nc) files
Import will allow you to transfer not only the geometry of the parts and its designation, but also the number of parts required for cutting, indicating the thickness of the material. Programs supporting the DSTV(NC) format - Tekla Structures, Advance Steel, StruCAD.

Optimization of cutting of various sheet materials is carried out in special programs, which helps to do everything correctly 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 running a business. Multi-user mode is supported, there is sorting and systematization of entered information, and data on materials and contractors is saved.
Implementing a warehouse will help you always be aware of the remaining amount of materials. There is a distribution into tables where active orders, planned orders and an archive are located; all information can be viewed and edited by the administrator. "Master 2" has several assemblies, one of them is distributed free of charge and 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 turns out to be well optimized; the user only needs to enter the required dimensions, select materials and specify additional settings, if necessary.
Cutting 3 provides users with the ability to use files from other programs, for example, loading parts from . In addition, visual design is supported.
Astra Cutting
"Astra Cut" simplifies the cutting process as much as possible. All you need to do is load the parts, indicate their dimensions and wait for the cutting map to be processed. Third-party and official libraries of furniture and other objects that are suitable for procurement in this way are supported.
We recommend that you pay attention to the presence of built-in documentation. It is systematized and formed as the work on the project progresses. Just go to the appropriate tab when needed and print any of the compiled 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 tried to select the most suitable and high-quality software.
Cutting is a program for cutting sheet materials: chipboard, glass, etc. The program for cutting chipboard allows you to reduce and optimize material consumption; it records waste, including “business” waste, which is not taken into account when calculating the cost of the order. The utility can be used in enterprises engaged in the mass production of cabinet furniture; for this purpose, the concept of ordering has been introduced into its functionality. All completed orders are automatically entered into the order database, and subsequently it is possible to repeat or change them. You can download Opening 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. Next, the program will independently select the optimal cutting option with the least amount of waste. If necessary, you can use the material database available in the program, which contains standard sheet or roll sizes. In this case, it is enough to specify the material to be cut, 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 total waste and increasing continuous cutting. Reducing overall waste means cutting with a minimum amount of scraps. The continuous trim increase mode, in addition to reducing waste, is used to create a maximum trim that can then be used for another order. You can also save on material by combining two orders if they use the same material.
The main advantages of the Cutting utility
- Two cutting optimization algorithms.
- Database of standard sheet sizes.
- Working with two types of edges.
- Works with both sheets and rolls.
- Database of completed orders.
During cutting, all cuts are made from one edge of the sheet to the other - either horizontally or vertically. The material consumed for cutting and other technological operations is taken into account when calculating 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 Cutting in online mode.

All you need to do is call us or write a message to our email, or leave your contact information by filling out the following form.
When creating an order for cutting, you can enter parts manually or import data from another program.An essential feature of specifying the initial data is the use of the alphanumeric part number and the name of the part in the product, which corresponds to its actual representation in the design documentation.
Library of standard products
The program allows you to describe a library of standard products and use them in the future when creating orders for cutting. You can reduce the time required to enter initial data for cutting by tens of times - a few commands and the order is ready for cutting.Pasting the edges of parts
For parts, you can specify the edges to be glued. At the same time, an arbitrary number of grades of material for gluing edges is supported. The entered information is used to calculate the quantity and cost of the material per order.When cutting glass or metal, this function is no less useful! In the same way, you can consider grinding the edges of parts for glass or cutting edges for welding for metal.
Optimal cutting
Automatic cutting of material is carried out taking into account technological and organizational parameters of production. The parameters allow you to set: cut width, cutting the edge of the sheet, taking into account through cuts, type of cutting, minimum distance between saws, etc.A unique set of customizable parameters is a distinctive feature of the Astra Cutting program.
When manually editing maps, a number of functions are provided for quick and accurate cutting adjustments: placing a group of parts to the width of the cut, alignment to a common base, shifting until it stops, etc. At the same time, canceling completed operations is supported, allowing you to restore the previous state of the cutting map, and scaling document windows.
