摘要

CAPP (Computer Aided Process Planning) has already become the bottleneck of CAD/CAM system . Present two-dimensional CAPP system which is used in the enterprise needs to be input information and data again , because it can not draw data from CAD ( Computer Aided Design ) model automatically after building CAD model and drawing. This has influenced extensive use of CAPP system because of its low efficiency. In this paper , three-dimensional model is built by using the parametric method, the process file can be produced directly through drawing corresponding characteristic and parameter from the model with the aid of process database. This improves the efficiency of product development. Visual C + + 6.0 and SQL Server 2000 are used to develop WTJDCAPP prototype system based on component model and SolidWorks three-dimensional CAD platform . Engine valve-seat is taken as concrete object to validate of the technology.
