Pro/Engineer, which is developed by United States Technical Parameters Company is a set 3D CAD software based on the parameters and the characteristics of 3D. Its mechanical design module is a high-efficient 3D mechanical design tool. At the same time, Pro/E also provides CAE module, but the CAE function is relatively weak and process of the treatments to the questions are very cumbersome. ANSYS software is a large scale finite element analysis software which is launched by the United States ANSYS company, it have a very strong analysis function, it is a multi-physical analysis software which is consist structure, heat, liquid, electromagnetism and acoustic in one whole function. It has a very rich and improved unit warehouse, material model warehouse and solution equipments. It can solve the problems accurately at a reasonable boundary and conditions. But its capabilities of fact modeling are limited, in most case, it need to import the models from the modeling software. These years, milling process is a cutting process technology; it has been wi
