【Abstract】 This paper is developed to the application of the finite element method in milling of wall-thin components. Meanwhile, it analyzes and calculates the deformation degree for the typical thin wall structure by using the software ANSYS 514. The results calculated conform to those from practical machining. As a result, the authors put forward a FEM-analysis-based method of NC compensations to reduce the errors caused by the deformation and maintain the machining accuracy.更多还原
