FAGOR五轴数控系统RPCP功能实现及应用

摘要

Due to influence of rotational motion, the non-linear error will be produced in 5-axis machining. RTCP/RPCP compensation function of 5-axis CNC system is introduced, upgrading and reformation process of FAGOR CNC System is described in this paper. Based on machining of typical parts, the rationality of reformation scheme is verified. By comparing machining processes, machining precision and efficiency with non RPCP function, the advantages of machine tool performance with RPCP function after reformed are verified.%五轴加工中由于旋转运动的影响,会产生非线性误差.文章介绍了5轴数控加工中RTCP/RPCP补偿功能,系统阐述了以FAGOR为代表的数控系统升级改造过程,通过数控系统的改造升级使其具备RPCP功能.以典型零件加工实例,验证改造方案的合理性,并通过与非RPCP功能在加工流程、加工精度和效率方面的对比,证明改造后具备RPCP功能机床性能的优越性.
