Abstract: |
To realize automatic processing of discontinuous internal surface of cabin and to increase processing efficiency and working accuracy, an atypical coordinate transformation algorithm of post-processing has been researched, post-processing system based on atypical NC milling machine has been designed and NC program has been written. Simulating manufacturing has been finished to verify validity and high efficiency of post-processing system, also as for machine structure characteristics and cutter interference problem, NC program has been completed. Through amending NC program, the final simulation result shows that NC program is efficient and makes NC milling processing come true. |
