摘要:
为提高模具型腔平面铣削的加工效率,提出了一种余料加工的方法,即进行2次加工,第1次选取半径较大的刀具快速切削大部分材料,第2次选取半径较小的刀具只对剩下的余料进行切削. 这样大大地缩短了加工时间,提高了加工效率. 分析了余料产生的位置,给出了余料区域的计算方法,生成了加工刀轨. 算法在Superman CAD/CAM 系统中实现,实践表明,算法稳定、可靠,具有很好的工程应用价值.
Abstract:
In order to promote planer milling efficiency, the pocket is milled in two operation. In the first operation the major material is cut away rapidly with big tool. In the second operation only the uncut material is milled with little tool while the futile tool trip is avoided. This method can reduce the milling time greatly. In the paper, the location of uncut material is pointed out, the method of caculation of uncut regions is provided and the tool path is generated. The algorithm is realized in the Superman CAD/CAM system. It is proved that the algorithm is stable and reliable. 
