Since its inception appears in 1998, has become the worlds most popular CAD / CAM 3D systems with standard software, the software is widely used in machinery, tooling, industrial design, automotive, electronics, aerospace, appliance and other industries. Pro / E is very powerful, it can be used as part design, product mix, mold development, NC (NumberControl CNC) machining, sheet metal design, casting design, design, reverse engineering, automatic measurement, motion simulation, stress analysis, and product database management. But Pro / E structure large number of modules, so it has some learning difficulties. Based on the stepped shaft design and contour roughing program settings, the first use of Pro / E for the overall design, and then by reference to the figure of the designed size limit and precision parts with appropriate modifications. In manufacturing, the use of turning and milling machining range planning window to NC sequence started from the processing of rough stock. By Pro / E module to use, understand and ma
