Principles should be followed in the arrangement of CNC processing sequence?

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 needs of positioning and clamping. The important point is that the rigidity of the workpiece is not destroyed. The sequence should generally follow the following principles:

1. The cnc processing of the previous process cannot affect the positioning and clamping of the next process, and the general machine tool processing processes should also be considered comprehensively.

2. Carry out the inner cavity procedure first, and then the contour processing.

3. It is best to connect the processes of cnc machining with the same positioning, clamping or the same tool to reduce the number of repeated positioning, tool changes and moving platen times.

4. For the multiple procedures carried out in the same installation, the procedure should first be arranged with less rigid damage to the workpiece.
