目前,加工变斜角带下陷一类零件多在三座标或四座标机床上进行,这固然方便;但在缺少三座标和四座标机床时,要加工这类零件,就有一定困难。我们在立足于本厂现有设备条件及总结以往数控加工经验的基础上,采用“行距法”一次算出刀具中心轨迹,避免了因下陷带来的分段处理,按此方 At present, it is convenient to process a variety of parts such as sag with a sag in the three-coordinate or four-coordinate machine tool. However, in the absence of the three-coordinate and four-coordinate machine tools, it is difficult to process such parts. We are based on the existing plant conditions and summarize the previous CNC machining experience, based on the use of “row method” to calculate the tool center trajectory, to avoid the subsidence caused by sub-processing, according to this square
