| Abstract: |
| A CAD/CAM software package for integrated blade of missile engine was presented for NC programming of integrated blade , which include blade design, cutter path file, base cutter path, automatic interference checking and angle setting, and display. The software has an interface to provide users input design data to obtain NC code. This application systems achieved any type blade CAD/CAM works of national crucial products. The result of product measuring shows that the software package is feasible. |
