Abstract

In the mechanical products, there are always some poor stiffness and high precision thin-walled workpieces which will produce deformation in the machining process easily, so it is difficult to control the machining accuracy and to meet the requirement of higher machining accuracy. Based the finite element numerical simulation key technology, this paper analyzes the machining deformation, including geometric model simplification, mode selection, dynamic loading, a 3D simulation model of thin plate features establishment. Through the finite element numerical simulation analysis of the thin plate, we analyze the influence on processing deformation from different processing parameters and different constraints.
