This paper discusses the process to apply the open-architectured intelligent manufacturing system to the sculptured surface cutting. The real-time method of compensation for cutting errors was presented. A tool deflection model is developed to calculate the corresponding horizontal tool deflection at the surface generation points on the cutter. The sensitivity of the machining errors to tool deflections has been analyzed via the deflection sensitivity of the surface geometry. The ability of the developed system was verified by a machining experiment, and the cutting error was reduced to about 1/3-1/4.
