An Algorithm for Determining the Nested Relation between Contours of Complex Parts Applied in Laser Cutting

Abstract:

Designed a method based on the complexity of multiple nested parts to extract and analyze the information of parts. In order to simplify the algorithm and improve the efficiency of the program, a data structure stored all information of entities was presented. The theory of the region method was introduced in this paper, and a specific algorithm was designed to judge the nested relationship between contours by using this theory and entities information. Finally, the computational result can be used to determine the contour cutting order.
