Analysis and Improvement of Thickness Compensation Defect of Body Stamping Parts

thickness Abstract：in compensation stamping of the parts space 3D surface measurement of stamping or machining parts. Wrong of CNC thickness positioning compensation blocks, it will is necessary lead to the to out-oftolerance do the defect of the body geometry, which is a dimension defect easily caused by human factors. This paper analyzes the causes of the defects, and concludes the precautions which should be observed to prevent such defects according to the actual case. These precautions have a reference for the technical personnel engaged in the body craft work and the CNC programmer of the body tooling processing. Key words: Thickness compensation, Body size, Defect improvement
