CAPP is the abbreviation of computer aided process planning. For a long time, the traditional manual process design inevitably has some defects: high requirements for process designers; Heavy workload and low efficiency: it is difficult to guarantee the accuracy of data; And information cannot be shared. At the same time, with the development of computer technology and its wide application in machinery manufacturing, computer-aided process planning came into being, and its breadth and depth are constantly developing. Generally speaking, CAPP is to use computer technology to assist process design and output process regulations, which can shorten the process design cycle, respond to design changes quickly and improve the work efficiency and quality of process departments. However, in order to meet the needs of CAD/CAPP/CAM integrated system and CIMS development, the understanding of CAPP should be further expanded, that is, a broad understanding: one end of CAPP is to optimize production plan and job plan, and as an important part of M, N; The extension of CAPP to the other end can generate NC instructions, which can serve as a bridge between CAD, CMA and MRlPl and become one of the technical foundations of many advanced manufacturing technologies.
Function: The function of CAPP (Computer Aided Process Planning) is to work out the processing technology of parts by computer, and process the blanks into parts required on engineering drawings. It is a process of inputting geometric information (shape, size, etc.). ) and process information (materials, heat treatment, batch, etc.). ) to the computer, and the computer automatically outputs the process documents such as the process route and process content of the parts. Computer aided process planning is usually translated into computer aided process planning. CIRP put forward the names of CAP(Computer aided Planning) and CAPP (Computer Automated Process Planning). The word CAPP emphasizes the automatic design of process.
