i5系统AC摇篮式五轴联动加工中心Power MILL后处理研究

Research on Power Mill post-processing of AC cradle type five axis machining center in i5 system

研究采用Power MILL软件平台及后处理构造器,以i5系统AC摇篮式五轴联动加工中心为试验研究对象,定制一款适合i5系统AC摇篮式五轴联动加工中心的后处理文件,以整体叶轮零件加工为例对后处理进行了试验验证,试验结果表明:使用该后处理产生的NC程序代码,通过Vericut软件仿真模拟和实际加工时未出现欠切、过切和报警等异常现象,加工后的叶轮尺寸公差和表面粗糙度能够达到Power MILL加工策略所设置的各项精度要求,验证了后处理的可行性和正确性,为其他数控系统和特种加工数控设备建立后处理研究提供了借鉴。

The research adopts PowerMILL software platform and post-processing constructor, takes AC cradle five-axle linkage machining center of i5 system as the research object, customizes a post-processing file suitable for AC cradle five-axle linkage machining center of i5 system, and takes impeller parts processing as an example to verify the post-processing.The test results show that the NC program code generated by the postprocessing can be used to simulate and alarm no abnormal phenomena such as undercut, overcut and alarm during actual machining by Vericut software. The dimension tolerance and surface roughness of the processed impeller can meet all the precision requirements set by the PowerMILL machining strategy, which verifies the feasibility and correctness of the post-processing, and also can be used for other CNC systems and special types.The research on post-treatment of CNC machining equipment provides reference.
