Computer Aided Process Planning System For Plastic Profile Extrusion Die

The producing characteristics of plastic profile extrusion die products are different from that of general products, which are smalllot and varieties, i.e. the products have their own individuation according to the requirements of consumers. In order to meet the needs of aspects above-mentioned, to enhance automation degree as possible, to improve its quality, to shorten its developing cycle must be reached by using advanced devices and means (e.g. computer) as we design and manufacture plastic profile extrusion die. Consequently, plastic profile extrusion die products can adapt to the requirements of market and competition. Therefore, the development of the computer aided process planning (CAPP) system for plastic profile extrusion die is very necessary and important.According to the current manufacturing situation of plastic profile extrusion die enterprises and the developing trend of CAPP system, a computer aided process planning system for the process design of plastic profile extrusion die was developed by using hybrid CAPP system, in which there are different decision-making functions of search, variant and generative. It employed different process planning methods in terms of different structures of plastic profile extrusion die. Several techniques, such as feature modeling, database, group technology, OLE, process PRI, were used to build the system. The system can partially realize the process planning of plastic profile extrusion die parts, therefore, the efficiency and quality of process planning can be improved, manufacturing cycle can be decreased.
