Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) are very vital elements of a Computer Integrated Manufacturing (CIM) environment and linking the two is equally important in improving the productivity of a manufacturing system. The link between CAD and CAM through human intervention is commonly referred to as manufacturing Process Planning. This paper presents an approach to Computer Assisted Process Planning (CAPP) of asymmetrical prismatic parts. The feature volumes are developed using both the constructive solid geometry approach and by sweeping the boundary faces along a direction depending on the machining operation. An algorithm is developed to recognize machining features and also calculates the machining volume. The features are recognized using the hint based and volumetric decomposition approaches. The algorithm is implemented using JAVA and STEP AP-203 translator to communicate with various CAD systems such as Pro-Engineer and Solid Edge. A database of tool material, work material, speed and combination is developed using Oracle 11 G Database. The integrated system consists of several stages such as operation selection, tool selection, machining parameter selection and cutting tool selection. The process plans are presented to validate the CAPP system. Keywords - Process Planning, Feature recognition, Productivity, Prismatic parts, Validation
