Abstract: Basic ideas and concepts of STandard for the Exchange of Product model data-compliant Numerical Control data interface (STEP-NC) were briefly introduced. The implementation strategies of STEP-NC based on Application Reference Model (ARM) and on Application Interpretation Model (AIM) were discussed and compared. The interface methods and technology for application system and STEP-NC were studied. Interface method for physical file of ARM and implementation method of file in AIM format were discussed in particular, and then implementation technology based on eXtensible Markup Language (XML) was also studied. Related technologies on STEP compliant NC programming and manufacturing were summarized. Finally, research progress and problems for the system were also pointed out.

Key words: numerical control machining, numerical control programming, standard for the exchange of product model data, integrated manufacturing
