Description

Technical Field

[0001] The present invention relates to the technical field related to laser cutting, and in particular to a nesting typesetting mixed common edge analysis method and system based on laser cutting. Background Art

[0002] Laser cutting machines generally have only one cutting nozzle. The cutting nozzle emits a laser beam to irradiate the material to be cut. After the material is heated to the vaporization temperature, holes are formed. As the cutting nozzle and the material to be cut move relative to each other, multiple holes are connected to form a cutting seam.

[0003] Before laser cutting, nesting layout is required. Nesting layout is to arrange the cutting processing contours of parts on a plate of a given size. During the laser cutting process, the common edge of the outer contours of two adjacent parts is only cut once by the nozzle, and no edge is cut repeatedly. This is because once the nested plate is cut, thermal deformation and movement will occur, and repeated cutting will affect the quality of the processed section.

[0004] In summary, through nesting and mixed co-edging, two or more parts can be co-edged into a combination, and large quantities of regular graphics can be co-edged as much as possible. Co-edging cutting can greatly shorten the cutting time and save raw materials.

[0005] In summary, the prior art has the technical problems of unreasonable nesting layout scheme, low utilization rate of raw materials and inability to ensure laser cutting efficiency. Summary of the invention

[0031] Based on the preset blanking process logic, the first positioning of the first preset cutting contour is obtained, specifically including: judging whether the preset material plate needs to be cut at intervals (if the material needs to be embedded in a certain position, that is, no interval cutting is required, the preset interval is set to 0; if the material needs to reserve a spacing, the preset interval is analyzed and the preset interval can be set to 0.5cm), and a first judgment result is obtained, and the first judgment result can be whether interval cutting is required / not required; determining the preset interval according to the first judgment result; adjusting the first preset cutting contour based on the preset interval, if necessary, extending the preset interval outward according to the preset cutting contour to obtain the first adjusted contour, and if not necessary, directly setting the preset cutting contour to the first adjusted contour; obtaining the first center point of the first adjusted contour, and using the first center point as the first positioning, obtaining the second positioning of the second preset cutting contour based on the preset blanking process logic (the technical solution is consistent and no repetitive description is given), preliminarily determining the nesting layout, and providing a data basis for subsequent nesting layout.

Based on the target layout constraints, after analysis through CATIA CPD software or FIBERSIM software, a sheet layout scheme set of the preset sheet is generated, and the sheet layout scheme set includes multiple sheet layout schemes; the first sheet layout scheme from the multiple sheet layout schemes is randomly extracted, and it is determined whether there is sheet overlap; if there is no sheet overlap, the first sheet layout scheme is added to the candidate layout list, the sheet layout scheme set is traversed to perform sheet overlap judgment, and a candidate layout list is generated to provide a data basis for subsequent layout scheme optimization.

[0056] S732-2: Obtain a first total area based on the first preset area and the first total number;

[0057] S732-3: Obtain a second total area based on the second preset area and the second total number;

[0058] S732-4: Add the first total area and the second total area to obtain a first comprehensive area;

[0059] S732-5: Obtaining a preset area of ​​the preset material plate, and obtaining a first proportion in combination with the first comprehensive area;

[0060] S732-6: Use the first proportion as the first verification result.

[0061] Specifically, the first candidate scheme is analyzed based on the first verification scheme to obtain a first verification result, which specifically includes: determining whether the first preset cutting contour is regular (regular: regular shapes such as rectangle, rhombus, triangle, circle, etc. whose areas can be directly calculated); if the first preset cutting contour is regular, directly calculating the first preset area of ​​the first preset cutting contour; if the first preset cutting contour is irregular, the first preset cutting contour is divided into regular shape areas and irregular shape areas, and the area of ​​the irregular shape area is calculated using calculus, and the area of ​​the regular shape area + the area of ​​the irregular shape area = the first preset area. According to the above method, the first preset cutting contour is calculated in sequence.

When the second judgment result is an empty cutting, perform empty cutting statistics to obtain the first empty cutting distance; use the first empty cutting distance (the smaller the first empty cutting distance, the shorter the unnecessary cutting stroke of the laser beam, the lower the cost of material processing, and the higher the efficiency of laser cutting) as the second verification result to provide support for reducing the processing cost of laser cutting.

[0070] Step S734 includes the steps of:

[0072] S734-2: Preprocess the first accumulated total number, the first verification result, and the second verification result to obtain a preprocessing result;

[0073] S734-3: Perform weighted calculation on the preprocessing result to obtain a first weighted calculation result;

[0074] S734-4: Replace the first comprehensive index with the first weighted calculation result.

[0075] Specifically, the first comprehensive index is adjusted according to the first verification result and the second verification result, specifically including: adding the first total number and the second total number to obtain a first cumulative total number; using normalization analysis, preprocessing the first cumulative total number, the first verification result and the second verification result to eliminate the indicator dimension (the data obtained after eliminating the dimension is a scalar) to obtain a preprocessing result, the preprocessing result includes a first cumulative total number preprocessing scalar, a first verification preprocessing scalar, and a second verification preprocessing scalar, and using the coefficient of variation method to analyze the preprocessing result. Weighted calculation, the coefficient of variation method is an objective weighting method, which directly uses the information contained in the first cumulative total number, the first verification result and the second verification result to calculate the weight (the weight includes the first cumulative total number weight ratio, the first verification result weight ratio and the second verification result weight ratio). After determining the weight, the first cumulative total number preprocessing scalar, the first verification preprocessing scalar and the second verification preprocessing scalar are weighted in turn to obtain the first weighted calculation result; the first comprehensive index is replaced by the first weighted calculation result to provide technical support for the difference in balance indicators.
