computer-aided process design;  Description of part information;  Parameters

In the computer-aided process design system, the accuracy, scientificity and comprehensiveness of the part information description will directly affect the quality and reliability of the designed process. A parameter-based CAPP part information description method is proposed, and taking shaft parts as an example, the description method of parameter-based CAPP part information is introduced in detail, and the whole input process of part information description parameters is given, so that the description and input of CAPP part information are simple and clear.
