Currently, most CAD systems, even the feature-based design systems which were developed for the need of CAPP, cannot provide exact information of an object (e.g., dimensions and tolerances). Some feature-based design systems can provide product data directly or indirectly; however, most CAPP systems still does not have interface with those CAD systems. The product data required by these CAPP systems usually has a specific format. In the CAPP system, it is essential for setup planning to ensure the precision of machining processes. Therefore, it is necessary to develop an interface with CAD models that the part data file can be obtained directly from CAD representation. This paper proposes an approach to integrate the setup planning system with a feature-based CAD system. By using an object-oriented approach - Product Data Translator (PDT), the compute-automated extraction of geometry and complete tolerance information is achieved; and the automated generation of tool approach direction was developed.
