An USB-based software CNC system

This paper presents an open architecture software-based CNC, and analyzes the hardware and software platform of the CNC system. In the hardware structure, Universal Serial Bus (USB), as the interface and protocol of the communication, is mainly emphasized. In the software structure, the paper first discusses the operating system in the control applications, then Linux and RT-Linux are selected, and finally the functions of the CNC system begin elaborated according to the module’s hierarchy.
