Complete tool collision checking and high speed machining will reduce polishing process of die-making. This paper describes a new method of numerical controller to realize such machining of sculptured surfaces. The two key technologies are proposed. One is tool projecting and dividing method, which decides tool positions by projecting the tool to the objective surfaces, and divides the projected area of the surfaces into a mesh and putting down the tool on the mesh at the given XY coordinates. The mesh is constructed of two-dimensional ring buffer in order to represest the tool motion. The other is application of parallel processing to machining of sculptured surfaces. Possibility of the realtime interpolation is discussed from the result of development of 32 bit multi-processor. As the results this paper concludes that the proposed method will be able to realize realtime machining with tool collision checking by parallel processing of the newest microprocessors.
