Method for generating laser cutting program

Abstract

The invention provides a method for generating a laser cutting program, which comprises: a step 1, acquiring digital graphic data of an object to be processed by using a camera and performing graphic pretreatment of the digital graph; step 2, manually defining a detection guide line in the pretreated digital graph, allowing a computer to extract coordinate data of graphic boundary points near the detection guide line under the guidance of the detection guide line, and forming a coordinate data link list of the coordinate data; a step 3, forming a graphic element data link list by using straight lines, arcs and parametric curve piecewise fitting coordinate data; step 4, smoothly connecting adjacent graphic elements by using a three-order Hermite parameter curve and filling the connected graphic elements into the graphic element data link list; step 5, converting the graphic element data link table into motion instruction of a laser cutter through post treatment and transmitting the motion instruction to a controller of the laser cutter to execute the motion instruction after the motion instruction is decoded. The method adopts machine vision and digital graphic processing technology to form main-machine interaction and therefore can generate a high-quality laser cutting program.

Description

technical field [0001] The invention relates to the field of laser cutting machine processing and programming, in particular to a method for generating a laser cutting processing program. Background technique [0002] At present, my country's laser processing industry is a new industry. In the past, the processing of the graphics required for laser cutting was performed by manually compiling machine codes. This manual operation is cumbersome and the work efficiency is low. With the advantages of modern computer development, the microcomputer control technology of machine tool laser cutting has also been paid more and more attention by people. Using microcomputer control technology, it is necessary not only to create a good interface environment for man-machine interface, simplify the operation, but also to fabricate processing software suitable for the graphics required by the microcomputer control of machine tool laser cutting, so as to achieve automatic conversion into ma...
