Process optimization modeling in generative CAPP

The aim is to realize the generation of the parts machining process and the process optimization based on the parts feature information, the machining information and the information of shop floor's resource. In generative CAPP, the method of expert system modeling is used to build the feature process, select the machine and the tool, and determine the machining parameters. The model of combinatorial optimization is established to put forward the model of feature ordering, process sequence and optimization. The technique of ODBC (open database connectivity) is applied to finish the connection of the different databases. Then the integration with CAD, MIS, PPS and the other subsystem can be realized. By the proposed method, the parts process planning, which meets the ability of shop floor's resource, has been generated to achieve the parts process optimization. This method has been used in the CAPP development for enterprises.
