Closed-loop manufacturing process based on STEP-NC

The paper proposes a new concept to support closed-loop manufacturing from CNC machines to CAD/CAM systems. The main goal is to manage knowledge from the CNC machine to the CAM system to help CAM programmer in making choices for planning new machining sequences. The STEP-NC standard enables bi-directional exchanges between all the manufacturing technologies in the digital chain—from CAD systems to CNC machines. Unfortunately, STEP-NC standard does not allow having a traceability of machining program. To achieve the information feedback from CNC machine to CAM system the proposal set up a manufacturing loop based on PLM systems. This proposal is based on OntoSTEP-NC model an ontology based on STEP-NC which provides trades between product data management, manufacturing process management and enterprise resource planning. As a solution OntoSTEP-NC aims at supporting data extraction from CNC machines, and relevant information integration into CAM systems. In order to have the most relevant information integration, a feature recognition stage has been introduced in the CAM programming stage. Moreover, coupled to case base reasoning, this recognition loop will allow filling the database of manufacturing process management. Last, this proposal will help CAM programmers in making choices for cutting conditions based on company best practices.
