【Abstract】 To improve the expansibility and intellectuality of computer aided process planning (CAPP) systems, a new model for process planning was proposed, based on the analysis of the characteristic and operating object of process rules. Design parameters and process resource parameters were associated by property-association in this model. Taking example for selecting tools and generating NC code automatically, the expression and execution of this model were also discussed. The traditionary design of process planning was optimized and expanded through this model, while the resource of design and manufacture was integrated better.更多还原
