对铸件毛坯侧壁窗框的加工,可在展开缠绕边界的基础上进行2D刀路设计,再利用CAM的旋转轴取代功能实现其到卧式四轴加工刀路的转换;实际加工时还必须先预测坯料余量分布的均匀性,并由此选择其铣切加工的刀路方案,对余量分布不均匀的状况做对刀设置的调整;同时,为获得满足要求的柱面铣切质量,对平底铣刀底刃质量提出了要求。
For the processing of the side wall sash of casting blank, the 2D path design can be carried out on the basis of expanding the winding boundary, and then the rotary axis of CAM is used to replace the function to realize the conversion to the horizontal four-axis machining path; in the actual machining, First, predict the uniformity of the billet margin distribution, and then select the milling program of the knife path, the balance of the uneven distribution of the knife set to do the adjustment; the same time, to meet the requirements of cylindrical milling quality , The quality of flat bottom milling cutter made the request.
