Embedded CNC system with the μc/os-Ⅱ OS

  • Received Date: 23 Mar 2005

  • An embedded CNC(computer numerical control) system and its hardware and software platform are presented. The system hardware consists of microcontroller ARM(advanced RISC machines) and FPGA(field programmable gate arrays). The CNC system application runs on the ARM, while FPGA is used to connect IO and generate pulses. The software platform utilizes the μc/os-Ⅱ OS to provide hard real time capabilities. The CNC controller software architecture which applies a generic open architecture model with a software bus is presented. Some important methods for carrying out the implementing of the CNC controller are researched and demonstrated, including thread cutting. Finally, a real machining experiment on the system mentioned above is introduced. The result shows that it can be successfully used in real manufacturing environment.
