[0053] The processor of the present invention is used to implement grouping processing of layout results based on double-beam cutting of a numerical control system, wherein the processor is configured to execute computer-executable instructions. When the computer-executable instructions are executed by the processor, the various steps of the method for grouping processing of layout results based on double-beam cutting of a numerical control system are implemented.

[0054] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the above-mentioned method for grouping and processing nesting results based on double-beam cutting of a numerical control system.

[0055] In a specific embodiment of the present invention, a method for grouping nesting results suitable for cutting parts of a double-beam machine tool is provided. The purpose is to divide the nesting results into two groups, upper and lower, relatively evenly. Two beams can cut the two groups at the same time, and the difference in their respective working time is small, thereby improving the efficiency of part cutting.

[0056] The present invention provides a method for grouping the layout results of double-beam cutting in a numerical control system, for a cutting machine tool with double beams, such as Figure 1 The following steps are included:

[0057] (1) According to the strategy of equally dividing the total length of the path, the parts after layout are divided into two groups, upper and lower, and the height of the dividing line between the upper group and the lower group is calculated, including:

[0058] (1.1) Sort the parts after arrangement from left to right and from bottom to top to form an ordered parts list P n (n is the total number of parts): Get the bounding rectangle of the part, then get the coordinates of the lower left vertex of the rectangle, according to the x and y coordinates

[0059] Values ​​are sorted from left to right and bottom to top;

[0060] (1.2) The parts are accumulated in order, and the path length is calculated after removing the duplicate edges: Set the path length list L n (n is the total number of parts), where the i-th element L i represents the total path length of the first i parts, Li -L i-1 represents the circumference of the i-th part

[0061] The length minus the length of the edge that the i-th part overlaps with the previous i-1 parts;

[0062] (1.3) The part closest to 1 / 2 of the total path length is the grouping boundary. The parts before this part in the parts list are

[0063] to the lower group, and the remaining parts to the upper group, such as Figure 2 As shown;

[0064] (1.4) Calculate the lowest point height H of the upper group UMin , and then calculate the height H of the highest point of the next group DMax , calculate the absolute value of the height difference between the two diff , which is the height of the dividing line between the upper group and the lower group;

[0065] (2) According to the strategy of dividing equally according to the arrangement height, the arrangement parts are divided into two groups, upper and lower, and the height fluctuation of the dividing line between the upper group and the lower group is calculated, including:

[0066] (2.1) Obtain the total height H of the sample arrangement result nest , with 1 / 2 of the total height as the grouping boundary;

[0067] (2.2) Parts whose lowest point is above the limit are grouped in the upper group, and the rest are grouped in the lower group, e.g. Figure 3 As shown;

[0068] (2.3) Calculate the lowest point height H of the upper group UMin , and then calculate the height H of the highest point of the next group DMax , calculate the absolute value of the height difference between the two diff , which is the height of the dividing line between the upper group and the lower group.

[0069] (3) Selecting the grouping result of the strategy with the smaller fluctuation height, specifically including: comparing the dividing line fluctuation height H of the grouping results obtained by the two grouping strategies diff , adopt the strategy with smaller fluctuation height. When the fluctuation height calculated by the two strategies is the same, it is preferred to divide the total length of the path equally. Figure 2 and Figure 3 The same sample arrangement result is divided equally according to the total length of the path and the sample arrangement height. After calculating the height of the dividing line, the priority is selected. Figure 3 The grouping results are shown.

[0070] The technical solution of the present invention provides a method for grouping the layout results of double-beam cutting in a numerical control system, which acts on the stage after the layout of parts and before the actual cutting.

[0071] The technical solution of the present invention is to use the total path length bisection strategy to calculate the total length of the part contour after removing repeated edges as the total path length based on the basic information of the part contour and part vertices.

[0072] The technical solution of the present invention makes an optimal selection among two grouping results obtained by dividing equally according to the total length of the path and by dividing equally according to the height of the row of samples.

[0073] The total path length bisection strategy described in the technical solution of the present invention is to calculate the total length of the part contour after removing duplicate edges as the total path length based on the basic information of the part contour and part vertices, and then divide it into two halves according to the total length. The purpose is to obtain the total length of the part after removing duplicates. The path described in the technical solution of the present invention is not an actual cutting path and does not consider empty strokes.
