摘　　要：研究如何在数控镗铣中心上通过铣削方法达到屏蔽主泵大尺寸螺纹孔的起始部位去除不全螺纹部分的加工要求。通过研究确定要加工的第一个全扣位置、加工起始点所在的加工区域、不同的加工深度、采用的铣削方法等,实现铣削不全螺纹的数控操作。此加工方法避免了手工操作的不安全性与不确定性。在装配过程中,避免了不全螺纹部分划伤主螺栓表面,且便于主螺栓与主螺纹孔对正,增加了装配的安全性、可靠性。It is studied how to use the milling method in NC boring and milling center to meet the requirement of removing the incomplete threaded parts at the beginning of the large size screw hole of the main pump. Through the study to determine the position of the first full buckle, the processing area in which the starting point is located, the different processing depth and the milling method adopted, the NC operation of the incomplete thread of milling is realized. This method avoids the insecurity and uncertainty of manual operation. In the assembly process, avoid the incomplete thread part to scratch the main bolt surface, and facilitate the main bolt and the main threaded hole to be correct, increase the safety and reliability of the assembly.
