Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Such as figure 1 As shown, the method for automatically optimizing the position of the cutting piece comprises the following steps:

[0024] S1. Carry out judgment on whether the internal cutting line of each cut piece forms a closed area in turn, if so, calculate the circumscribed rectangle of the closed area and then execute step S2; otherwise, continue to execute step S1; when holes need to be cut out on the cut piece, then The edge of the hole is the stitch that needs to be cut, that is, the inner cut line. Only when the cut stitch is a closed area connected end to end, the fabric in the closed area will be cut and pulled out to form a hole. Therefore, it is judged that the inner cut of the piece is Whether the...

Abstract

The invention provides a method for automatically optimizing positions of cutting pieces and belongs to the technical field of cutting control. The method is used for solving the problem of fabric waste due to the fact that the fabric as a hole in the existing cutting pieces is treated as a waste material. The method comprises the following steps of S1, sequentially judging whether a closed area is formed in the internal cutting line or not for each piece; S2, sequentially calculating an external rectangle for each cutting piece and judging whether the external rectangle is accommodated in theexternal rectangle of the closed area or not; S3, moving a first target cutting piece and aligning a center point thereof with a center point of the abovementioned closed area, and judging whether the first target cutting piece is completely located in the closed area; S4, moving a second target cutting piece to an edge of the closed area, subtracting a contour of the closed area from a contour of the second target cutting piece to obtain the remaining contour and taking the remaining contour as a new closed area, and repeating the step S2; and S5, repeating the step S1 until all of the pieces are completely judged. The method has the advantages of high fabric utilization rate and low cost.

Description

technical field [0001] The invention belongs to the technical field of cutting control, and relates to a method for automatically optimizing the position of cutting pieces. Background technique [0002] In the garment production process, the cut pieces are first cut out from the fabric by the cutting bed, and then the cut pieces are sewn into garments. Due to the needs of clothing design, one or several larger holes are often formed in the cut pieces, such as the back part of a lady's swimsuit. The current processing method of the hole is directly treated as waste. The problem is the waste of fabric, especially the large hole area. Contents of the invention [0003] The object of the present invention is to solve the above problems, and propose a method for automatically optimizing the position of the cutting pieces. [0004] The purpose of the present invention can be achieved through the following technical solutions: a method for automatically optimizing the position ...
