Selection of jig tool and determination of cutting amount

Determination of cutting amount

In NC programming, programmers must determine the amount of cutting for each process and write it to the program in the form of instructions. Cutting parameters include spindle speed, back feed and feed speed. For different machining methods, different cutting parameters are needed. The selection principle of cutting amount is to ensure the machining precision and surface roughness of the parts, give full play to the cutting performance of the tool, ensure the reasonable tool durability, and make full use of the performance of the machine tools, maximize the productivity and reduce the cost.
