Facing the trends of the computerized numerical control (CNC) systems towards multifunction and high integration possible leading to real-timeness and robustness problems caused by condensed information exchange, an open CNC system configuration was proposed based on Profibus-DP and PXI buses. The time behavior of the buses was analyzed, it was found they meet the demand for high speed and high precision. The controller uses the IPC framework, accomplishes the software function using the component technology, realize the rapid reconstruction of CNC by different allocation of functional components. The functions of state monitoring, failure diagnosis and processing optimization are fused into the CNC system using a 3-layer network. The prototyped machine based on IPC framework proved the feasibility of the CNC scheme.
