摘　　要：为了解决当前切削加工机器人控制系统中存在的开放性、智能化和集成化程度低的问题,将STEP-NC标准引入机器人加工领域,构建了基于STEP-NC的切削加工机器人后置处理系统.基于STDeveloper软件开发了高效的信息提取类库STNCLib,提出了基于等照度线的复杂曲面分区刀具轨迹规划方法.在此基础上研究了机器人运动控制程序的自动生成方法,并最终生成机器人运动控制程序,实现机器人控制系统的信息集成.采用软件编程和仿真的方法对所提方法的正确性和有效性进行了验证,结果表明所提方法是合理和可行的.In order to solve the low degree of openness, intelligence and integration existing problems in the machining robot control system, the STEP-NC standard was introduced into robot machining field and the machining robot post processing system was constructed based on STEP- NC. The efficient information extraction library-STNCLib which proposed the tool path planning method based on iso-photo line was developed based on ST-Developer software. The robot motion control program was generated finally, and it could achieve information integration. The correctness and effectiveness of the proposed method was verified by using the software programming and simulation method, the result shown the reasonability and feasibility.
