| 摘 要： | 在UG前置处理输出的刀位文件的基础上,针对AC回转工作台式五轴联动数控机床结构,分析了后置处理中重要的机床运动轨迹坐标变换;就加工表面曲率变化较大时,旋转自由度大幅摆动导致加工表面质量下降的问题,提出了进给速度修正的方法.并论述了数控系统SIEMENS 840D特有的钻削循环类指令的后置处理方法.所开发出的后置处理程序的正确性通过在BV-100机床上某叶轮样件的加工得到了验证.

| Abstract: | Based on cutter location file generated by UG Pre-Processing,five-axis machine equipped with AC rotary workbench is objective,coordinate transformation of machine trajectory which is the major part of post processing is analyzed.Feed rate rectification is proposed to avoid surface quality decline due to rotary degree swinging when process surface curvature changing greatly.Post processing of instructions of drilling cycle on SIEMENS 840D CNC system is discussed.Post processing program is developed and valid... |
