The processing sequence shall be arranged according to the structure of the parts and the condition of the blanks, as well as the need for positioning and clamping, with the focus on ensuring that the rigidity of the workpiece is not damaged.
Generally, the sequence shall follow the following principles:
- The CNC processing of the previous process shall not affect the positioning and clamping of the next process, and the general machine tool processing process shall also be considered comprehensively.
- The internal shape and cavity processing procedure shall be carried out first, and then the external shape processing procedure shall be carried out.
- It is better to connect the CNC machining processes with the same positioning, clamping method or the same tool to reduce the number of repeated positioning, tool change and moving the pressing plate.
- For multiple processes carried out in the same installation, the process with little damage to the rigidity of the workpiece shall be arranged first.
