Abstrakt

The paper presents the information flow between CAD/CAM/CNC systems when using the CNC machine tool programming language based on ISO 6983. Next, the data structure of the new programming standard STEP-NC, defined in ISO 14649, is presented. The information flow for this new standard is also discussed. The results of analysis show how this standard can be used for the increase of the automation of CNC machine tool programming.
