A framework for process planning and NC programming based on STEP and STEP-NC data model is proposed in this paper. The STEP standard and its data structure for CAD models, especially the NURBS based representation of complex surfaces is analyzed. Then the general strategy for process planning using the STEP-NC data structure is presented, and the calculation of cutter contact points and cutter location data for producing complex surfaces based on the geometrical information is addressed. Finally a prototype system is developed for demonstration of the proposed STEP-compliant NC programming approach for complex surface components.
