The Research Of Open Cnc Platform Based-on Motion Controller

The Open-CNC system based on motion controller is a hot spot in recent years.And more and more system integrators develop their CNC system using motion controller. But the motion controller only provides the basic function of motion control, so the system integrators have a lot of work to do to develop a CNC system. This paper aimed to set up an open CNC platform, which provided most of the basic functions of CNC system, to simplify the system integrator's work. In this paper, the Open-CNC platform was studied, specifically including the following aspects: the platform architecture and the key modules of the platform.Platform architecture is the abstract description of the overall functions and structure for the platform. This paper presented a layered architecture for CNC system. It divided the CNC system into real-time control layer, NC platform layer and application layer. Based on this architecture, the structure of the Open-CNC platform based on GTS motion controller of Googol Company was studied, as well as its functions, communication model and interface of NC platform Layer. Meanwhile, some important function modules of this Open-CNC platform were also realized in this paper, such as code interpretation, cutter compensation and tool-path optimization. And all of the function modules committed to the communication model and interface of NC platform layer mentioned above.
