Abstract

The invention discloses a geometric simulation method in the virtual laser flexible processing course. The method comprises the establishment of a virtual processing platform, the trajectory planning based on CAD data, the trajectory optimization, the triangular simplification algorithm based on processing head effect, and a collision detection model. The invention can help observe the processing movement course in the computer visualization environment, visually display the collision interference and unreasonable processing trajectory in processing robots and other equipment as well as workpieces by laser, and forecast the processing defects in an early stage, so as to provide an effect basis for process parameter adjustment and process optimization, so as to save manpower, material resources, time and cost.

Description

technical field [0001] The invention relates to a simulation method, and more specifically, the invention relates to a geometric simulation system and an implementation method of laser flexible processing. Background technique [0002] Virtual manufacturing is a combination of modern manufacturing technology, computer graphics, concurrent engineering, artificial intelligence, artificial reality and other high-tech. It models and simulates all manufacturing environments and manufacturing activities. It is a simulation of the entire life cycle of products. . The process simulation is the bottom layer and core of virtual manufacturing. Due to the many factors involved in the machining process, the process is complex, and it is difficult to integrate the research on the machining process into the large simulation system of virtual manufacturing, which has always been one of the bottleneck problems of virtual manufacturing. The geometric simulation of the processing process can...
