UG NX软件的FANUC系统车铣复合加工后处理器研制
Development of UG NX Post-processor in Turn-milling Machining with FANUC System

计算机辅助编程中,不同CAD/CAM软件的后处理器是不同的。借助于UG后处理构造器,根据FANUC 18i系统极坐标编程和圆柱坐标编程原理,分别针对轴向端面加工和径向圆周加工两种工况,研制了两套适用于FANUC 18i系统的车铣复合加工后处理。为了考证后处理器的可行性和可靠性,针对一中等复杂程度的车铣复合零件,在UG CAM环境下进行了前处理、计算机加工仿真和后处理,在Spinner PD型车铣机床上进行了铝合金切削实验。考证试验表明,针对FANUC系统开发的后处理器可靠性好,在轴向端面加工和径向圆周加工两种不同工况下能够无差错的进行NC代码转换,特别适合实际生产中复杂零件的计算机辅助编程,有应用推广价值。
The post-processing method is different among general CAD/CAM software in computer-aided programming. In this paper, according to the principles of polar coordinate programming and cylindrical coordinate programming of FANUC 18i system, we develop two sets of post-processing for turn-milling machining by UG Post Builder for axial processing and radial processing cases, respectively. To verify the reliability and availability of the software,the turn-milling operations and machining simulations were made for a complex part in UG CAM module,and two experiments of cut aluminum alloys in PD/C-TMC CNC machine tool of SPINNER company were conducted. The results and their analysis showed preliminarily that the CNC programming converted by the post-processors can be executed directly in FANUC system without any errors. It is proved that the two sets of post-processing are highly reliable, particularly suitable for the actual production in turn-milling machining and valuable for wide spread applications
