(1) Roughing stage. Most of the machining allowances are excavated for each machining surface, and the standard for machining is refined, and the main consideration is to increase the productivity as much as possible.
(2) Semi-finished product stage. Defects that may appear after rough machining, to prepare for surface finishing, require certain machining accuracy, ensure appropriate finishing allowance, and complete secondary surface machining.
(3) The finishing stage. At this stage, high cutting speed, small feed and cutting depth are used to remove the finishing allowance left by the previous process, so that the die-casting surface of precision aluminum parts can meet the technical requirements of pattern.
(4) The finishing stage. Mainly used to reduce the surface roughness value or strengthen the machined surface, mainly used for surface machining with high surface roughness (ra≤0.32μm).
(5) Ultra-precision machining stage. The machining accuracy is 0.1-0.01μm, and the surface roughness value ra≤0.001μm. The main processing methods are precision cutting, fine mirror grinding, precision grinding, polishing, etc.
