Study on Cutter 3D Wear Shape Based on 3D Measurement and Hybrid Modeling

The 3D shape of tool wear part is the important information to study the reasonability of geometric parameters of cutting tool and to analyze the reason of tool wear.3D point cloud data of wear tools were gained by 3D optical scanning measurement technique.The 3D shape of tool wear part was achieved by mixed data processing of solid models and point models.By means of contrast of 3D models and point cloud data,the chromatograms and distortion analysis reports of tool changes before and after wear were gained.The analysis steps of turning carbide insert 3D wear shape were given,to prove the feasibility and validity of the method.
