Problems solved by technology

The existing one-size-fits-all rectangular raw material sheet layout blanking method cannot meet the "one-size-fits-all" process requirements, and the processing is difficult. The "one-size-fits-all" process requires cutting from one end of the rectangular plate to the other end along a straight line, and dividing it into Two independent rectangular parts, the cutter can only go in a straight line, and cannot turn or stop during the cutting process, that is, each cut wil

Example Embodiment

[0058] Example one:

[0059] The rapid layout method for rectangular workpieces facing single-size sheets of this embodiment, such as figure 1 As shown, including the following steps:

[0060] Step 1, the step of traversing workpieces, input the initial data of several rectangular workpieces to be arranged, and traverse the initial data of all rectangular workpieces to be arranged;

[0061] Step 2, the step of layout of the first rectangular workpiece, quickly recommend a piece of the rectangular workpiece as the first rectangular workpiece, and discharge it, and discharge the first rectangular workpiece according to the lower left, lower right, upper left or upper right as priority. The first rectangular workpiece is placed on the lower left corner, lower right corner, upper left corner or upper right corner of a single rectangular plate;

[0062] Step 3. The step of dividing the area to be nested is to cut the single plate along the long or short side of the first rectangular workp...

Example Embodiment

[0114] Embodiment two:

[0115] The rapid layout method of rectangular workpieces for single-specification plates was tested in the first embodiment, and 21 test case sets were designed. In each test case set, the specifications and quantities of the rectangular workpieces are different, and the specifications of the single plates are also different. , Testing the rapid layout method of rectangular workpieces for single-specification plates of this embodiment corresponds to the number of single plates to be used in each test case set, the utilization rate of the overall layout scheme and the layout time, and the test results As shown in Table 1:

[0116]

[0117] Table 1

[0118] As shown in Table 1, all 21 sets of test cases can find the optimal solution with a utilization rate of 100%, indicating that the rapid layout method for rectangular workpieces for single-size plates can quickly find the optimal solution for the test case. With good climbing characteristics, the layout dia...

Abstract

The present invention discloses a rapid stock layout method of rectangular workpieces for a single specification board. The rapid stock layout method comprises: (1) a workpiece traversal step of inputting initial data of a plurality of to-be-arranged rectangular workpieces, and traversing the initial data of all the to-be-arranged rectangular workpieces; and (2) a first rectangular workpiece stock layout step of rapidly recommending and arranging a rectangular workpiece as the first rectangular workpiece, arranging the first rectangular workpiece with priority arrangement sequences of left lower, right lower, left upper and right upper, and putting the first rectangular workpiece at a left lower corner, a right lower corner, a left upper corner or a right upper corner of a rectangular single board. According to the rapid stock layout method of rectangular workpieces for the single specification board, a 'clean cut' process requirement is satisfied by a blanking stock layout process, stock layout speed is fast, the total utilization rate of the board is high, manufacturing cost of enterprises is largely reduced, requirements of the enterprises on multispecies concentrated blanking are satisfied, and great benefits are brought for blanking production and selection of the manufacturing enterprises.

Description

technical field [0001] The invention relates to the field of blanking and layout methods for plates, in particular to a rapid layout method for rectangular workpieces facing single-size plates. Background technique [0002] In the fields of sheet metal processing, glass processing, furniture manufacturing, clothing tailoring, etc., it is often necessary to cut rectangular workpieces of various specifications on a single-size rectangular raw material plate, so how to perform layout blanking on a single-size rectangular raw material plate To improve the utilization rate of raw materials has become a matter of great concern to the production of enterprises. The existing one-size-fits-all rectangular raw material sheet layout blanking method cannot meet the "one-size-fits-all" process requirements, and the processing is difficult. The "one-size-fits-all" process requires cutting from one end of the rectangular plate to the other end along a straight line, and dividing it into T...
