回转体逆时序右特征识别及内外轮廓自动重构
Automatic recognition of inner and outer contours of rotary body parts using most right recognition algorithm
摘要
Abstract
Extractions of internal and external contour information of revolving parts is of great importance to enable auto-matic generation of NC machining codes.This paper puts forward an automatic recognition algorithm for inner and outer contours of revolving parts via the"clockwise-rightmost"discriminant method.Information related to the geometric enti-ties,saved in the systematic text structure in DXF,combined with the symmetry information of the revolving body parts, is utilized to the elimination of the redundant features such as the dimension marking, profile lines, roughness marking, form and position tolerance marking,etc.Finally the clockwise rightmost discrimination algorithm is used for the recogni-tion of the contour anticlockwise.The algorithm demonstrates many advantages,especially the reduced computational com-plexity,therefore can identify the internal and external contour of the part effectively and robustly.关键词
