This paper presents an overview about standard representation of product data for better communication and exchange between CAD/ CAM systems. For mechanical parts, standard use for description of product data is ISO 10303- Product data representation and exchange, also known as STEP. This make possible to use standard data during design, process planning and production stage to integrate CAD and CAM. The main barriers to realizing this concept is most of computer numerical control (CNC) machines, which use ISO 6983 G/M codes language. G/M codes lack the portability because of the following reasons. First it focus only on tool center path rather than machining process, second some vendors use language supplement with their own extensions programme which make it ambiguous. ISO 14649 called as STEP-NC is a new standards which extend STEP standard for NC. STEPNC replaces G/M codes by remedies the above shortcomings. STEP-NC specifying machining processes rather than machine tool motion, using the concept of working steps. Working steps correspond to high-level machining features and associated process parameters. The controller of future CNC’s are responsible for translating Working steps to axis motion.
