STEP-NC based optimization and smart industrialization of NC machining in the context of the factory of the future

The paper proposes a new concept to support information feedback from CNC machines to CAM/NC simulation systems. The main goal is to manage knowledge from the CNC machine to the NC simulation to provide guidelines and help programmers in making choices for planning new machining sequences. The proposal uses a feature oriented approach for knowledge capitalization. As STEP-NC which is manufacturing features oriented, is not implemented yet, the proposal is based on actual manufacturing technologies and proposes a feature recognition directly on STL file from NC simulation and proposes to convert G-Code to STEP-NC in order to interact with OntoSTEP-NC, an ontology based on STEP-NC, implemented as a knowledge database.
