Programming methodology for multi-axis CNC woodworking machining center for advanced manufacturing based on STEP-NC

The paper proposes a programming methodology for advanced manufacturing based on STEP-NC, a compliant to multi-axis CNC woodworking machining center. The equivalent virtual machine in the CAD/CAM, STEP-NC environment, is developed as a part of a programming system for considered CNC woodworking machining center. STEP-NC aims to provide a digital thread for CNC manufacturing running in the STEP-NC System world via the Internet that can enable advanced e-Manufacturing. Virtual machine as a digital twin is configured and implemented into the control system based on LinuxCNC, but configured virtual machine as a Web interface based on STEP-NC, also. The developed methodology is validated through machining simulation using the configured digital twin in the control system and machining experiments on the real machine.
