Treatment of numerical control milling and its treatment are sequential treatment of milling of arrangement numerical control is sequential arrangement treatment includes cutting to machine working procedure, heat treatment working procedure and auxiliary working procedure to wait normally orderly, the science that working procedure arranges will affect the treatment quality of the spare parts, productivity and finished cost directly. Cutting machines working procedure to press arrangement of the following principle normally: (1) first thick hind treatment of precise and appropriate should pass level of rough machining, semifinishing machining, finish machining when demand of spare parts precision is higher, if precision demand is higher, still include numerical control milling treatment is sequential arrangement treatment includes cutting to machine working procedure, heat treatment working procedure and auxiliary working procedure to wait normally orderly, the science that working procedure arranges will affect the treatment quality of the spare parts, productivity and finished cost directly. Cutting machines working procedure to press arrangement of the following principle normally: (1) first thick hind treatment of precise and appropriate should pass level of rough machining, semifinishing machining, finish machining when demand of spare parts precision is higher, if precision demand is higher, still include to do a few level such as treatment solely. (2) principle of datum plane go ahead of the rest uses as the surface with fiducial essence should be machined first. The treatment process of any spare partses always is opposite first fixed position is standard have rough machining and precision work, for example axis kind the spare parts always is first machining center aperture, it is essence of life with central aperture again the circle outside standard treatment and end panel; Casing kind the plane that the spare parts always machines fixed position to use first and aperture of two fixed position, it is essence of life with plane and fixed position aperture again department of standard treatment aperture and other plane. (3) first the aperture after the face wait for a spare parts to casing, bracket, planar dimension outline is bigger, compare stability with planar fixed position, and the depth size of aperture is it is with plane fiducial, reason should machine plane first, machine aperture next. (4) first advocate hind second machine main surface first namely, machine less important surface next. CNC Milling
