摘要
在快速制造金属模具工艺中,采用工业机器人对具有复杂形状的模具型腔进行抛光加工,开发了基于CAM软件模块的机器人抛光轨迹自动规划系统.该系统利用UG CAM软件中的多轴铣加工功能模块获得型腔的表面信息,然后采用辅助区域驱动法在复杂型腔表面映射生成连续的多轴数控加工轨迹,然后根据抛光工艺要求调节工艺参数,并将多轴数控加工轨迹转化成机器人抛光加工轨迹.实验结果表明,该系统所生成的抛光轨迹可满足面向复杂模具型腔的机器人抛光加工要求.
Industrial robots are used to polish the mold cavities with complex shapes in rapid metal tooling technology. An automatic path planning system based on CAM （computer-aided manufacturing） module is developed for robotic polishing process. The surface information of the cavities was obtained through the multi-axis milling module of the UG （unigraphics） CAM software, and the multiaxis numerical control （NC） milling track was mapped by the assistant area driving method. The NC milling track was finally transformed to the robotic polishing path after the track was adjusted by the parameters according to the requirement of the robotic polishing technology. The experiment result shows that the robotic polishing path generated by the system can meet the requests of the robotic polishing for the complex mold cavities.
