Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 2 As shown, the greedy program module GREEDY () programming method is as follows:

[0030] The first step is to judge whether the feature points in the array S containing punching point information are more than 1, if not more than 1, the program ends, and if more than 1, the program continues;

[0031] The second step is to find in S the point with the shortest distance to the last point in array T, then program this point into T, and delete this point from S;

[0032] The third step is to return to the first step to judge;

[0033] Such as figure 1 As shown, the steps of using the greedy algorithm to write the tracking path planning optimization method program are as follows:

[0034] The first step is to write a program to compile the information of all "punching points" into the array S in order, and pay attent...

Abstract

The invention provides a seeking route plan optimizing method of a laser cutting machine. The method comprises the following steps that: 1, a program writes the information of all the 'punching points' into an array S according to sequence; 2, the points in S are judged and optimally sequenced, if the points are less than 2, the program is terminated, and if the points are more than 2, the program is continued; 3, the point closest to a ruling end point is taken as a start point, is written into an array T and is then deleted from the array S to generate a new array S; 4, a greedy program module GREEDY () is called until all the points are processed by the greedy method to generate a new route point array T; and 5, a cutting program is written back according to the sequence of the punching point optimized in the array T to acquire the optimized cutting program. By the method provided by the invention, the automation degree of the laser cutting machine can be improved; the positioning is accurate; the idle stroke is shortened to the largest extent; the cutting time is shortened; and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, in particular to an optimization method for a tracking path of a laser cutting machine. Background technique [0002] Steel cutting is the most basic process in the manufacturing process of many large-scale mechanical equipment, and it is often the first process. The cutting efficiency will directly affect the subsequent processes. With the increasing use of CNC laser cutting machines, improving the cutting efficiency of laser cutting machines has become the main direction of research. The quality of the cutting path planning of the program used by the CNC laser cutting machine will directly affect the cutting efficiency. Optimizing the cutting path planning can effectively improve the cutting efficiency. The path optimization method refers to the establishment of an effective mathematical model, so that the controller According to the path designed by this mathematical model, instructions...
