The depth of cut is mainly limited by the rigidity of the machine tool. The cutting depth should be as large as possible if the machine tool stiffness is allowed. If the machining accuracy is not limited, the cutting depth can be equal to the machining allowance of the part. This will reduce the number of passes.
The spindle speed is determined by the cutting speed allowed by the machine and the tool. It can be selected by calculation or table lookup.
The feed rate f (mm/r) or the feed rate F (mm/min) is selected according to the machining accuracy of the part, the surface roughness, the tool and the workpiece material. The maximum feed rate is limited by the machine stiffness and feed drive and CNC system.
When selecting the cutting amount, the programmer must select the cutting amount that suits the machine's characteristics and the optimum durability of the tool according to the requirements of the machine manual and the tool durability. Of course, it is also possible to use an analogy method to determine the amount of cutting by experience. Regardless of the method used to select the amount of cutting, the durability of the tool must be ensured to complete the machining of a part, or to ensure that the tool durability is not less than one work shift, and the minimum can not be less than half a shift.
