Abstract :
STEP-NC (formalized as ISO 14649 and ISO10303 AP238) is a new interface standard between CAD/CAM and CNC, currently under establishment. Upon completion, it will replace ISO6983 (G & M codes). To study implementation technology for STEP-NC, a virtual system for 3D milling machining was established, which can take STEP-NC program as input. A functional architecture for this system is first proposed, and then followed by the software design for each constituent module. The key implementation technology involved includes: (1) STEP-NC program interpretation, (2) entity recognition, (3) entity mapping, (4) tool path planning, and (5) machining simulation. By a test for an example program, the correctness and validity of this system can be proved
