What regulation should be followed for the arrangement of cnc machining order?

2020-06-16

The arrangement of the processing sequence should be considered according to the structure of the part and the condition of the blank, as well as the need for positioning and clamping. One of important thing is that the rigidity of workpiece is not destroyed.

1、Cnc machining of the previous process cannot affect the positioning and clamping of the next process, and the processing process of the general machine tool interspersed in the middle should also be considered comprehensively.

2、First,Carry out the inner cavity and inner cavity , then the outer shape processing

3、It is better to carry out the processing with the same positioning, clamping method or the same tool cnc machining in order to reduce the number of repeated positioning, the number of tool changes and the number of moving the pressure plate.

4、For the multiple processes performed in the same installation, the process with little damage to the workpiece rigidity should be arranged .
