Abstract

STEP-NC was designed to replace ISO 6983 G-codes with a modern, associative communications protocol that connects computer numerical controlled (CNC) process data to a product description of the part being machined. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649 or also known as STEP-NC. The combinations of implementation methods and application protocols defined in STEP and STEP-NC standards provide standardized physical file formats and data access interfaces for those physical file formats that can cover all the aspects of design and manufacturing activities. The data exchanges between different systems will no longer have barriers through the implementation of STEP-NC in the computerized manufacturing environment. It will provide the missing link between CAD to CAM applications. This paper will review ISO 14649 which is STEP-NC through an understanding of STEP which is ISO 10303 standard for the computer-interpretable representation and exchange of product manufacturing information.
