<strong>Abstract</strong><br>
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.
