摘要：STEP-NC (ISO 14649) is a new feature-based machine tool control language between CAM and CNC. In contrast with conventional G&M code (ISO 6983), it could provide richer and more machining information for CNC controller at shop floor. Therefore, it's feasible to develop an embedded micro process planning module in CNC controller. Meanwhile, some other information models such as manufacturing resources are essential for completing the intelligent process planning. The main thrust of this paper is focused on two fields: i) Proposition of a framework for STEP-NC compliant controller, ii) Development of knowledge base with OWL for the process planning in CNC controller. A novel STEP-NC compliant controller named OntoStep CNC is presented, which could accept ISO 14649 machining models and then generate optimized tool path based on knowledge base and rules at the shop floor level.
