Research Status of Manufacturing Process of Thin-walled Workpiece

Research on preventing deformation methods of thin-walled workpiece during manufacturing is an important topic in modem manufacturing. In this paper, the structure characteristics of thin-walled workpieces are introduced and the influencing factors are analyzed. It shows that the material and structure, clamping technology, cutting force and cutting heat, residual stress are the main causes of thin-walled workpiece deformation, based on which the correspond- ing control methods are summarized with the technology development trend is given in the end. Only by concerning the whole causes of thin-walled workpiece manufacturing, combining theoretical modeling, simulation analysis and test can the deformation problem be better analyzed and controlled to improve the pass-rate and manufacturing quality of produc- tion. The work in this paper provides a reference for preventing deformation of thin-walled workpieces.
