The program for cutting wood chipboard online without registration. b) Extension of segments. The main advantages of the Cutting utility
An essential feature of specifying the initial data is the use of the alphanumeric part number and the name of the part as part of the product, which corresponds to its real representation in the design documentation.
Library of typical products
The program allows you to describe a library of typical products and use them in the future when creating orders for cutting. You can dozens of times reduce the time required to enter the initial data for cutting - a few commands and the order is ready for cutting.Pasting the edges of parts
For parts, you can specify the edges to be pasted. At the same time, an arbitrary number of grades of material for pasting edges is supported. The information entered is used to calculate the quantity and value of the material to order.When cutting glass or metal, this function is equally useful! Likewise, you can take into account the grinding of the edges of parts for glass or the preparation of weld edges for metal.
Optimal cutting
Automatic cutting of material is carried out taking into account the technological and organizational parameters of production. The parameters allow you to set: the width of the cut, trimming the edge of the sheet, taking into account through cuts, the type of cutting, the minimum distance between the saws, etc.A unique set of adjustable parameters is a distinctive feature of the Astra Nesting program.
When manually editing maps, a number of functions for fast and accurate cutting adjustments are provided: placing a group of parts on the cutting width, aligning to a common base, shifting to stop, etc. At the same time, the cancellation of performed operations is supported, which allows restoring the previous state of the cutting map, and document scaling.
Complete accounting of measured residues after cutting
The calculation of the residuals after cutting is performed both automatically and in the dialogue mode. Depending on the set parameters, the residues are automatically cut in the following orders. When working with a list of residues, they can be added, removed, sorted or filtered by any of the characteristics: size, grade of material, fiber.All ordering documentation
For each cutting plan, a complete set of technological documentation is formed - a sketch and a specification, including the necessary information for the manufacture of parts and accounting for the work performed. The cutting map is printed in any scale set by the user and in any orientation of the sheet. You can also set the output of several nesting plans on one printed sheet. In addition, the following documentation is generated: order specifications, material availability list, specification for pasting the edges of parts, invoice of work performed and materials on order, labels for marking parts.Postprocessors for CNC cutting machines

Importing data from a furniture design software
A great way to bring your design ideas to life in 3D is to use. In a few minutes you will develop a project and open it just as easily in the Astra Nesting program.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 several representatives of such software for you.
"Master 2" provides users with great opportunities not only in drawing up a cutting project, but also in conducting business. The multi-user mode is supported, there is sorting and systematization of the entered information, data on materials and contractors are saved.
The implementation of the warehouse will help you to always be aware of the remaining amount of materials. There is a distribution into tables where active orders, scheduled and archived are located, the administrator has access to all information 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 turns out to be well optimized, the user only needs to enter the required dimensions, select materials and specify additional settings, if required.
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 Cut
Astra Nesting simplifies the nesting process as much as possible. All you need to do is load the parts, indicate their dimensions and wait until the cutting plan is finished processing. Supports third-party and official libraries of furniture and other objects that are suitable for procurement 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 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 - 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", which are not taken into account when calculating the cost of the 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 order database, subsequently it is possible to repeat or change them. You can download Cutting for free on this site.
To start working with the utility, you need to set the dimensions of the sheet and the parts that will be cut from it. Then the program will independently select the optimal cutting option with the least amount of waste. If necessary, you can use the base of materials available in the program, which contains the standard sizes of sheets or rolls. In this case, it is enough to set the material for cutting, and the utility will automatically calculate according to the standard sheet parameters.
The nesting program works according to two main algorithms for optimizing chipboard consumption - reducing overall waste and increasing continuous trimming. Reducing overall waste means cutting with a minimum amount of scrap. The Increase Continuous Cut mode, in addition to reducing waste, is used to create maximum cut, which 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.
- Work with both sheets and rolls.
- Database of completed orders.
During nesting, 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 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 the network mode.
You can also cut sheet material manually, but it takes a lot of time and special skills. It is much easier to do this by using companion programs. They will help you optimize the nesting plan, suggest other layout options and allow you to edit it yourself. In this article, we have selected several representatives for you who do an excellent job of their task.
Astra Nesting allows you to work with orders by importing their blanks from the catalog. There are only a few templates in the trial version, but their list will expand after purchasing a program license. The user manually forms a sheet and adds details to the project, after which the software automatically creates an optimized cutting plan. It opens in the editor, where it is available for editing.
Astra S-Nesting
The next representative differs from the previous one in that it offers only a basic set of functions and tools. In addition, you can add only pre-prepared parts of certain formats. The cutting plan will only appear after purchasing the full version of Astra S-Nesting. In addition, there are several types of reports that are generated automatically and can be printed immediately.
Plaz5
Plaz5 is outdated software, has not been supported for a long time by the developer, but this does not prevent him from performing his task efficiently. The program is quite easy to use, does not require any special knowledge or skills. The cutting plan is created quite quickly, and the user is only required to specify the parameters of parts, sheets and design the card.
ORION
The last on our list will be ORION. The program is implemented in the form of several tables, into which the necessary information is entered, and then the most optimized cutting map is created. Of the additional functions, there is only the ability to add an edge. ORION is distributed for a fee, and a trial version is available for download on the official website of the developers.
Cutting sheet material is a rather complicated and time-consuming process, but this is if you do not use special software. Thanks to the programs that we reviewed in this article, the process of drawing up a nesting map does not take much time, and the user is required to make a minimum amount of effort.
The program is designed for a comprehensive solution to 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 solution approach used in the program summarizes the experience of a number of companies operating thermal cutting machines.
Database usage
The program integrates the traditional Tekhran processing programming tools with a database. The database is responsible not only for the task of managing various data, but also for managing the operation of the system as a whole, since sheet cutting programs are also objects of the database. First of all, details are entered into the database that can be imported from another system, built using Techran's tools or created on the basis of macros.
Creating parts based on macros
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, setting the actual values \u200b\u200bof the parameters. The program allows you to use parameterized parts when creating a part in the database. The parameters of the parts are entered in the dialog box. Users have the ability to develop macros that describe geometry and, if necessary, the processing of typical parts. It is also possible to define a description of the parameters to customize the dialog box and control the input data.
Fixed incorrect geometry when importing DXF files.
The system implements the ability to adjust the precision of contour filing when importing DXF files. Mate accuracy - the distance within which the mismatch of the original segments is permissible, which is eliminated when they are converted to contours. The precision of the fillet affects whether closely spaced segments are combined into one path or not. If the boundary points of the segments do not coincide, but the distance between them is within the fillet accuracy, such segments are filleted (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) Offset of segments “Short” segments (having a length less than the mating accuracy) are eliminated.
After deleting the "short" segment, the adjacent segments are conjugated. Segments (or portions of segments) that overlap each other within the fillet precision are combined. It is convenient to view the details simultaneously with a list of all the details. To manage parts and other objects of the database, Tekhtran offers a single visual mechanism 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 items (parts, sheets, sheet cuts, etc.) on the adjacent panel. In addition, the presence of two panels makes it convenient to work with objects, which in turn include other objects. So, for example, a sheet nest contains details. To organize the viewing of parts related to different sheet nesting, in one panel you can display a list of sheet nests, and on 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 ability to automatically and manually place parts of the task on cutting on sheets. At the same time, the program keeps track of the number of unplaced parts and the possibility of manufacturing a part from the selected sheet.
Automatic nesting of parts on a sheet
In automatic nesting mode, the program nests the job details on the sheets in an optimal way. The required additional sheets can be automatically taken from the warehouse. The program also allows you to automatically place the 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 a very high material utilization rate. The user has the opportunity to choose the optimal ratio between the quality of the placement of parts and the calculation time. With automatic nesting, you specify how the parts are compacted on an incomplete sheet. This affects the shape 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 place in voids within parts, or not fill holes at all.
Place parts manually 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 the nesting task and placed on the sheet, and then moved to an empty space using the graphical editor. There are also facilities for precise control of the relative position of objects. The combination of automatic and manual part placement allows you to take advantage of each mode for the most efficient operation.
Control of movement of parts
In manual placement mode, the program takes over a number of useful functions. These include various ways of moving parts in compliance with 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 movement of parts.Enabling this function allows parts to move 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 movement of parts. With preventive control, the movement of parts is not limited to the free area of \u200b\u200bthe 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 \u200b\u200bthe sheet. In other words, this operation moves the part in a certain direction until it rests against the part or the edge of the sheet.
Copy parts back to back.
When copying parts in this mode, the distance is automatically determined by which the part can be moved in the specified direction so that the parts are located close to each other.
Aligning the sides of parts allows you to orient the parts in such a way as to match them with the selected sides.
Aligning parts in a straight line. This is useful when positioning parts for through cuts.
Processing programming
After the parts are placed on the sheet, processing is programmed. In the simplest case, it is enough to sequentially indicate the contours of the parts to be machined. The program builds the tool path, taking into account the necessary corrections, generates approaches, offsets and auxiliary tool movements, commands for turning the cutter on and off, feed, offset, etc.
Approach and exit.There is a possibility of various settings for the methods of approaching the contour being machined (along a straight line, along an arc, along a normal, along a tangent, etc.), choosing an approach point (automatically or explicitly) and operating modes of the cutter at various stages of processing.
Jumpers. On the contour of the part, non-cut areas - jumpers can be selected. When constructing the trajectory, the program automatically generates in such places the commands for turning the torch on and off and embeds the approach and exit sections.
Bridges between parts allow you to machine multiple parts without turning off the torch. The transition points of the path from one part to another are specified after placing the parts and are taken into account when building the final path of the torch.
Hinges provide high-quality cornering 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 in order not to repeat the same actions for multiple inclusion of elements in the nest.
Handling processingyu. For non-standard cases, it is possible to construct a trajectory and assign technological commands in an explicit form.
Subroutines provide structuring of the received control program and reduce the volume of the generated text.
Processing of 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 torch. When machining individual parts, it is sufficient to indicate the contour of the part to be machined first.
Pre-piercing.When machining thick sheets, it may be necessary to first punch holes in the sheet and then do the basic processing. Either a separate cutter or a drill can be used for this pretreatment of the sheet. The program allows you to perform machining with preliminary hole punching. There is a possibility of specifying different methods of preliminary piercing.
Positioning over the material. In some cases, it is necessary to move the cutter when moving from contour to contour, 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 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 machining mode makes it possible to maximally simplify the programming of machining a large number of parts. The program itself assigns the sequence of traversing the parts on the sheet and performs processing. Various walk-around strategies ensure that the required machining conditions are met.
Preparation of edges for welding
Cutting of edges for welding can be done on thermal cutting machines equipped with three-cutter blocks. The program provides the ability to process parts with both constant and variable chamfers. A permanent chamfer is characterized by constant 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 cutter's path of movement special sections - cut-in windows in the places where the side cutters are switched on and the cutter reversal loops, which ensure the correct orientation of the side cutters and the observance of the necessary processing conditions. The position of the cutout windows can be changed using a graphical editor.
Sheet layout
Marking on the sheet can be done using powder or core. Marking 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 work of the marking block, it is enough to indicate the marking contours in the required sequence. The program will make all the necessary switches and build the trajectory.
Multi-support processing
On machines equipped with multiple supports, several 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 machining, the required caliper routing is performed automatically.
Use of business waste
Business waste is formed from the unused part of the sheet, which can be placed in a database for later use.
Documenting
The program generates the following output documents:
- nesting chart
- sheet cutting specification
- specification of the cutting task.
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 setting the format of documents and the amount of information displayed.
Automatic text generation
In the process of constructing geometric objects and designing a 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 for further work. This allows you to flexibly combine the convenience of the interactive 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 typical parts
- Using conditional operators, loops, arithmetic expressions and functions
- Debug and bug fixes
Development and debugging tools
The system includes a set of tools for working with the program in Tekhtran language:
Execution commands (execute an operator, go to a macro, execute 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 in whole or in parts, pausing the process to analyze the results of the execution of individual statements.
Implementation controls make it possible to view the values \u200b\u200bof 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 Tekhran, allows to generate control programs for various CNC machines according to the part processing program and data about the equipment included in the system. Using the part program received for one machine, you can get the NC for any other machine from the equipment list.
Customization for specific CNC equipment
Tekhtran provides the ability to customize for specific CNC equipment. To describe the equipment, it is required to fill in the machine passport and create a machine module in a special language of Techpost. Such a mechanism allows users to independently take into account the peculiarities of the formation of the PM, developing their own modules based on the existing ones.

Batch processing
Batch processing has been implemented - a mode of operation in which a number of actions are automatically performed on sheet nesting. 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 mode, the following actions can be performed:
- checking the correct arrangement of parts on the sheet
- automatic processing of parts
- checking the resulting trajectory for gouging
- obtaining contours of business waste, cutting maps, control programs, processing statistics, specifications for cutting sheets
- export of parts and paths
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. The solution cost estimate takes into account:
- the cost of the sheets to be cut;
- the cost of business waste;
- scrap cost;
- slag cost;
- cost calculated based on:
- total processing time (includes depreciation of equipment and staff salaries);
- number of punctures (includes consumption of nozzles, gases, energy);
- cutting path / time (includes consumption of nozzles, gases, energy).
- path / time of idling (includes gas consumption, energy).
The cost is calculated separately for each sheet cut.
The costs can be summed up for the specification of the cutting order.
The cost can be allocated to 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 (optional).
|
|
Using the library allows you to:
- get sweeps of parts with the required characteristics
- using the preview window to 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 part - 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.
- split the part into several fragments if necessary
- select elements and assign geometric and technological parameters in the dialog mode
- automatically generate sweeps taking into account the bending radius
- quickly view and change options for unfolding
- view 3D models of the resulting joints
Using the duct element library will allow:
- reduce the design time of reamers
- take into account the technological features of element connections
- get high accuracy of building sweeps
- 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 cutting, indicating the thickness of the material. DSTV (NC) support programs - Tekla Structures, Advance Steel, StruCAD.
