(1) The processing of the previous process cannot affect the positioning and clamping of the next process.
(2) First inside and then outside, that is, the inner cavity (inner hole) is processed first, and then the outer shape is processed.
(3) The process of processing with the same installation or using the same tool should preferably be carried out continuously to reduce errors caused by repositioning or tool change.
⑷In the same installation, the process that has less influence on the rigidity of the workpiece should be carried out first.
