A Series Of Products Research And Development Of The Capp System

As the weak part of unit technologies in manufacturing, computer aided process planning-CAPP is vital in manufacturing information construction, and also a pinch point when integrated with other unit technologies.The importance of CAPP based on computer integrated manufacturing system is expounded after the current condition of our country's information construction is analyzed. With this, the aim and meaning to develop CAPP system is discussed in this paper. Integration of CAD/CAPP is also studied. According to product characteristics of Guangdong Huaiji auto-accessories manufacturing inc. LTD, method used in this paper is put forward. Key technologies of developing CAPP of pieces of series products are mainly discussed, including methods of process planning, construction of decision model of process, calculating of process dimension,System frame of HJ-CAPP is brought forward based on manufacturing status in Guangdong Huaiji auto-accessories manufacturing inc. LTD, and database server is built on CAD/CAPP integration. Structures of system and all the models and the flowcharts of main models are set up. The program of user management and process decision is given in Deiphi6.0 to verify the accuracy of the model and the practicability of the decision system.Giving first place to enterprise's applying and combining practicability with advanced theory is the guidance in developing the system. Building up the database server actualizes data communicating between CAD and CAPP and data management. One of the characters of this CAPP system is to use all kinds of methods of designing process and expressing knowledge in expert system.
