Control method of cutter idle stroke path during clothing piecing and cloth sample cutting process

Abstract

The invention discloses a method for controlling an idle stroke path of a cutter during the cutting of piece goods and pattern pieces of garments, which comprises the following steps: a, a population is initialized to randomly generate GSIZE individuals; b, a path length corresponding to each current generation individual is calculated to judge whether the a terminal condition is satisfied, a step g is executed if the terminal condition is satisfied, otherwise the operation enters a step c; c, an adaptability function is utilized to calculate the adaptability of each individual, and the timesthat each individual can be copied are determined by copying the function; d, the crossover and mutation probability is adjusted according to the diversity of the current generation individuals; e, mutation and crossover operations are performed on the current generation individuals; f, a heuristic algorithm is utilized for local search to improve the quality of the individuals and enter the calculation of next generation, and the step b is executed; and g, an optimal idle stroke path of the cutter in the current generation individuals is selected as a minimum value Min(Path) to be output. The method simplifies the calculation, greatly improves the speed of evaluating an approximate optimal solution, and has better optimization effect.

Description

technical field [0001] The invention relates to a method for controlling the empty stroke path of a cutter during the cutting process of clothing cloth and samples. Background technique [0002] When cutting clothing and samples, there are usually multiple contours to be cut, and each contour is usually composed of multiple line segments, and some point coordinates are used to form a contour. A contour consists of as few as 3 or 4 points, and as many as hundreds of points. When the tool wants to cut a contour, first select a certain point in the contour as the cutting start point, then traverse all the points on the contour in a clockwise or counterclockwise order, and finally return to the cutting starting point to complete the cutting of a contour. It is precisely because there are multiple contours and one contour has multiple points, if you want to cut all the contours, you must choose a cutting starting point on each contour to form a path of cutting machine tool empty...
