摘要
用并联机床加工汽轮机叶片时 ,往往受其工作空间的限制而不能在最佳的切削姿态下进行加工。因此我们在并联机床六轴联动的基础上 ,再串联一个数控转台 ,实现七轴联动 ,即可在一次装夹过程中 ,以最佳的切削姿态完成叶片汽道型面、叶顶、叶根圆角、进、出汽边圆角的加工。
While machining turbine blade simply by Parallel machine Tool(PMT), NC program development is often limited by workspace of PMT,and it is difficult to process at the best posture.In order to solve this problem,it is necessary to mount an additional NC rotary axis on PMT,and construct a 7 axis NC system.In this way,steam passage surface,blade tip,blade root rounding,inlet and outlet side rounding can be processed at the best posture by clamping the workpiece only once.The coordinate conversion formula for 7 axis Hybrid system and programming simulation method of the post processing is also presented in this paper.
