Study on Open CNC System Platform Architecture and its Application

Abstract

On the market today, the hardware and most software of CNC system are not exclusive and incompatible, and the system institutions vary, which makes the control systems of different manufacture relatively independent, closed to each other. In order to break this situation, this paper conducted a project design on the hardware and software of CNC system which is based on PC platform. On the hardware, ultimately determine the NC embedded PC architecture, design and motion control card based on PCI bus; in the aspect of software design, use Windows2000/XP operating system to achieve multitasking real-time CNC control, and design the software in the Visual C++ environment .Using the platform to achieve the application of the laser welding system, the design is proved to be feasible, it also reflects the basic idea of the open architecture.
