(1) of working procedure differentiate to machine a spare parts on numerical control machine tool, working procedure can compare concentration, complete much or whole process as far as possible in holding clip. Common working procedure differentiates have the following kinds of kind: 1) by the spare parts way of the orientation that hold card differentiates working procedure because figure of structure of every spare parts is different, the technique that processes the surface each asks to also differ somewhat, when reason is machined, its locate means has difference each. When processing an external form commonly, less than form locates; Locate with the appearance again when the form inside treatment. Consequently but according to orientation way different will differentiate working procedure. A shape cam that shows like graph 2-17 place, can divide by orientation way for two working procedure, the first working procedure can undertake on general accuracy machine tool. Round face and B plane locate beyond machine end panel A and Φ 22H7 inside aperture, next the craft aperture of B of rework end panel and Φ 4H7; Two Konghe that the 2nd working procedure crosses with already was being machined fixed position of an end panel, face curve is expressed outside cam of the milling on CNC Milling. Graph 2-17 piece the spare parts that turning of 2-18 of shape cam graph machines 2) thick, finish machining differentiates working procedure is mixed according to the treatment precision of the spare parts, stiffness be out of shape because always differentiates,wait when working procedure, the principle that can part by thick, finish machining will differentiate working procedure, namely first rough machining again finish machining. Right now usable and different machine tool or different cutting tool undertake machining. Be in normally in installation, after allowing to end treatment of surface of part of spare parts some, the other surface of rework spare parts. Be like the part that graph 2-18 place shows, answer to excise the major surplus of whole spare parts first, again vehicle of its surface fine, in order to assure the requirement of treatment precision and exterior surface roughness. 3) delimit with cutting tool by place foreword of division of labor changes knife time to decrease, reduce time of light locomotive trip, reduce needless fixed position error, the method that can center working procedure by cutting tool machines a spare parts, be in namely in outfit clip, use as far as possible same all position that give cutting tool treatment to be machined possibly, change another knife to machine other position again next. This kind of method is used in machine tool of special numerical control and machining center middling. (2) of labor situation differentiate of labor situation differentiate to basically be mixed from treatment precision two respects consider efficiency. Often need to use different cutting tool and cutting dosage inside a working procedure, undertake machining to different face. Describe more complex process to facilitate the analysis is mixed, inside working procedure fractionize is labor situation. A principle that will explain labor situation differentiates is with machining center below: 1) same appearance presses rough machining, semifinishing machining, finish machining ordinal finish, or full treatment surface is pressed first thick hind finish machining undertakes apart. 2) the spare parts that bores hole to having mill face again already, can bore hole after mill face first, make its have period of time to restore, can decrease by be out of shape the influence of the to aperture precision that cause. 3) differentiate by cutting tool labor situation. Time of circumgyrate of workbench of certain machine tool is shorter than changing knife time, can use differentiate by cutting tool labor situation, change knife time in order to decrease, improve treatment productivity. Anyhow, of working procedure and labor situation differentiate should ask to wait for a circumstance to consider integratedly according to the structural characteristic of specific spare parts, technology.
