Abstract
Aiming at the problems of low accuracy,long design cycle and poor reverse modeling effect of product surface defects in traditional reverse modeling of cam parts,a reverse modeling method based on the combination of contact(CMM)measurement and non-contact 3D scanner data collection is proposed.All features of cam parts are collected by non-contact 3D scanner,and key features are measured by CMM to obtain the feature data of cam parts.The feature data are imported into UG software for reverse modeling,and finally the precision of the reverse modeling is analyzed.The results show that this method can effectively solve the reverse modeling problems of high accuracy and appearance defects,and provide a reference for the development of similar products.关键词
