(1) Rough machining stage. Remove most of the machining allowance from each machined surface and establish the primary datum features. The primary consideration at this stage is to maximize productivity as much as possible.
(2) Semi-finishing stage. This stage removes any defects that may have been left over from rough machining and prepares the surface for fine finishing. It requires achieving a certain level of machining accuracy, ensuring an appropriate amount of material remains for subsequent fine finishing, and simultaneously completing the machining of secondary surfaces.
(3) Finishing stage. In this stage, a high cutting speed, a small feed rate, and a small cutting depth are employed to remove the finishing allowance left over from the previous machining step, thereby ensuring that the part’s surface meets the technical requirements specified in the drawing.
(4) Fine finishing stage. This stage is primarily used to reduce surface roughness values or to strengthen the machined surface, and is especially suitable for surface finishes with very high roughness requirements (Ra ≤ 0.32 μm).
