Abstract: In this paper a computer aided manufacturing (CAM) system for industrial robot machining operations is introduced. The system is based on the new machining standard STEP-NC which is rapidly making its way into the world of numerical controlled (NC-) machines (e.g. milling and turning machines). Existing research, related to STEP-NC development, focus mainly on the typical implementation of the standard into these traditional production equipments. However, industrial robots are getting more and more capable of taking onto machining operations and it is necessary to couple the industrial robot towards the new standard.
