Feature based automatic CNC code generation for prismatic parts

This paper reports the design and implementation of PRISPLAN - a generative feature based process planning system for prismatic components. The system comprises two important modules - a solid based feature modeller and the automated process planning module for CNC code generation. The feature based modeller provides an interactive graphical environment for part synthesis, while the process planning module facilitates automatic generation of error free CNC codes for machining the component. The system has been tested for several industrial components. It provides a user friendly environment for the rapid creation of error free CNC part programs
