What principles should be followed in the arrangement of CNC machining sequence?

    The arrangement of processing sequence should be considered based on the structure of the parts and the condition of the blank, as well as the need for positioning and clamping, with the focus on ensuring that the rigidity of the workpiece is not damaged. The order should generally follow the following principles:

1. The CNC machining of the previous process should not affect the positioning and clamping of the next process, and if there are universal machine tool machining processes interspersed in the middle, comprehensive consideration should also be given.

2. First, proceed with the machining process of the inner shape and cavity, and then proceed with the contour machining process.

3. It is best to connect CNC machining processes with the same positioning, clamping method, or the same tool to reduce the number of repeated positioning, tool changes, and moving the pressure plate.

4. Multiple processes carried out in the same installation should first be arranged to minimize the rigid damage to the workpiece.
