Abstract: With STEP-NC object oriented programming standard, the next generation of CNC machine tools promises to be more open, intelligent and interoperable. As this ISO standard totally integrates CNC controllers into the CAD/CAM/CNC numerical chain, it provides an opportunity to stand as a common data model for various manufacturing processes. This paper first proposes a multi-process manufacturing approach by using STEP-NC as the optimal data model for process planning, process specificities and inter-processes simulations. Then, experimental validations are ensured by the advanced CNC platform for multi-process manufacturing developed in the laboratory. Finally, the realisation of a part on the platform by using the multi-process manufacturing concept shows the efficiency of the proposed approach.
