1. How to divide processing operations?

The division of NC machining processes can generally be carried out according to the following methods:

3. For parts prone to machining deformation by rough and finish machining sequence method, the shape needs to be calibrated due to the possible deformation after rough machining. Therefore, generally speaking, the processes should be separated for rough and finish machining. To sum up, when dividing the process, we must flexibly grasp it according to the structure and manufacturability of the parts, the function of the machine tool, the number of NC machining contents of the parts, the installation times and the production organization of the unit. In addition, it is suggested to adopt the principle of process concentration or process dispersion, which should be determined according to the actual situation, but we must strive to be reasonable.
