Description
Summary:The process design is a very important step in NC machining which will ensure the manufacturing quality of the part. For the low rigidity part, due to the low rigidity and high deformation under certain load, herein, the low rigidity part often shows more clamping deformation under clamping force and cutting force in manufacturing, so that it will lead to machining error out of tolerance. In this paper, we choose a low rigidity shell part as research target, the machining process will be designed and analyzed, two clamping schemes were designed for this part, and the comparison and analysis were finished by using finite element method (FEM), the results showed that the smaller deformation and error was obtained in the axial clamping scheme, therefore, we choose this scheme as the ultimate clamping scheme for the low rigidity shell part.
