The production characteristics of China's compressor manufacturing industry and the status quo of CAPP application In China's compressor manufacturing industry, due to the rapid development of new technologies and new processes, social demand tends to diversify, and market competition is fierce, forcing the product renewal cycle to be shortened. The production mode and characteristics of most enterprises are: (1) multi-variety, small batch, manufacturing system is gradually shifting from rigid (planned mass production mode) to flexible (user-oriented multi-variety single-piece or small-batch production mode); 2) Most of the equipment used in production is a general-purpose machine tool, and rarely uses special equipment. Generally, the dimensional accuracy is ensured by scribing and trial cutting; (3) the enterprise is affected by the requirements of the user, the manufacturing tasks and management work often change, and the special parts Many and rapid changes, the process personnel must prepare various process documents according to different requirements, the amount of repeated labor is large, the consistency of the process documents is poor, the programming speed is slow and difficult to optimize. The production characteristics of the compressor manufacturing industry determine the dynamics, repeatability and complexity of its process design. The traditional process design method, because each process specification has to be manually written, a large amount of time is spent on the writing and filling process cards, the design efficiency is low, the process preparation cycle is long, and it is not convenient for the computer to unify the process technical documents. Management and maintenance make it difficult to bring together the experience and knowledge of process experts to make the most of them. Moreover, due to the limited experience of each craftsman, the habits are different, the technical level is also different, the consistency of the prepared process rules is poor, the quality is not easy to stabilize, and it is difficult to achieve the optimization goal. Therefore, for the compressor manufacturing industry, it is urgent to improve the process design level and solve the process bottleneck problem.
