 The standard step-in-c, ISO 14649, offers a new model for data transferred between CAD slash CAM systems and CNC machines. It addresses the limitations of the existing G-code standard and opens up new possibilities for its management. At the Department of Automation and Production Systems at the Faculty of Mechanical Engineering, University of Zalina, a project was conducted to explore the implementation of step-in-c format through programming of CNC machines. The results of this research included an analysis of the standard step-in-c, a methodology for converting step-in-c data into express code, and the development of software for transforming step-in-c data into a format compatible with a specific CNC machine controller. The software was tested on a particular CNC machine and successfully demonstrated the viability of implementing the new standard in older models.
