Method and device for automatic cutting trajectory generation of flexible material zero-pitch typesetting

Abstract

The application discloses an automatic blade cutting track generation method and device for a flexible material zero-interval layout graph and a computer readable storage medium. The method applied toa cutting bed comprises the following steps: extracting outermost layer path information of each cutting piece in a zero-interval layout graph of a to-be-processed flexible material to obtain an outer contour track sequence set comprising a plurality of processing paths; combining overlapped line segments of all processing path by comparing position information of all sequence points on each twoprocessing paths; determining a cutter eye processing mode on each processing path based on the position relationship of each cutter eye mark, and determining a cutter starting point position of an adjacent cutting piece by utilizing a preset cutter starting point selection method; and automatically generating a cutting track according to the cutter eye processing mode, the cutter starting point position and the track sequence set after combining processing. On the basis of not sacrificing the utilization rate of the fabric, the zero-interval layout cutting pieces of the flexible material areefficiently processed with high quality, so that the batch production requirements of flexible materials such as clothing and vehicle decorations are met.

Problems solved by technology

[0003] It is understandable that the use of zero-pitch typesetting graphics can significantly improve the utilization rate of fabrics, but the graphic tracks of clothing and automobile trim processing are diverse and complex

When processing the piece data of zero-pitch typesetting, two adjacent pieces to be processed will have the following problems: the flexible material after vacuum adsorption has a certain rigidity, and after track cutting, it will be damaged due to air leakage and material softness. The local inhomogeneity of the processing material caused by characteristics such as deformation and easy deformation leads to low cutting quality of the fabric; when cutting the layout map that has been arranged with zero spacing, if the starting point of the adjacent pieces is not handled properly, it will be damaged by the blade. The width of the adjacent pieces will cause damage to the adjacent pieces, which will cause cutting quality problems; the processing of the alignment marks on the overlapping line segments of the adjacent pieces will damage the cutting quality and cutting efficiency of the adjacent pieces.

However, increasing the space between the layout pieces will reduce the utilization rate of the fabric. The more pieces on the same layout picture, the greater the space required, and the lower the fabric utilization rate.
