Receiver part complex surface numerical control machining method

Abstract

The invention provides a receiver part complex surface numerical control machining method and belongs to the machine manufacturing field. The method adopts a segmental machining method, solves the difficulty of complex surface numerical control machining, and meanwhile, provides a thinking direction for resolving similar problems. According to the method, through analyzing part structure features, a machining surface is manually divided into a plurality of areas, and influences of different surfaces on cutters during programming are fully known; operation is established for different machining areas, thereby simplifying the programming process; and solution schemes are made for the influences, so that cutting points of the cutters are optimized, machining quality of the parts is improved, machining effect is improved, and the problem that the machining field is blank is fundamentally solved.
