Briefly describe the characteristics of derived capp system

The characteristics of derivative CAPP system are: based on group technology, it is mature in theory; Wide application range and good applicability; Widely used in rotary parts; Inherit and apply the mature traditional technology of the enterprise, but the flexibility is poor; Complex parts and parts with poor similarity are difficult to form part families.

Basic principle of derivative CAPP: Based on group technology, the system classifies parts into families according to the similarity of geometry or process, and establishes typical process rules of parts in this part family, that is, the processing methods, processing equipment, tools, fixtures, measuring tools and their processing sequence required for parts processing in this part family. The specific content can be determined according to the development degree of the system.

CAPP (Computerized Processing Planning) refers to the formulation of parts processing technology with the help of computer software and hardware technology and supporting environment, and the use of computer functions such as numerical calculation, logical judgment and reasoning.

With the help of CAPP system, the problems of low efficiency, poor consistency, unstable quality and difficult optimization of manual process design can be solved.
