Abstract: This paper overviews the STEP-NC data model,groups and analyzes the manufacturing related information contained in the STEP-NC part program,discusses issues related to the manufacturing data conversion from EXPRESS to C++ and their extraction from the STEP-NC file,models the feature-based geometry simulation of the NC machining process and discusses related techniques.On this basis,a STEP-NC supporting platform is developed in the ST-Developer environment.It can interpret the STEP-NC files,extract,reorganize and display graphically the manufacturing data,and simulate the machining workingsteps.
