摘　　要：砂轮在磨削工件时一般是线接触,但若砂轮形状得当,在磨削过程中每一个瞬时可以做到实际参与被磨削工件最终形状的是一个磨削点,原则上可以控制"磨削点"磨削出要求的曲线和曲面形状,因此提出了点磨削快速成形新原理。作为应用特例,对椭球面钻型进行快速成形刃磨。此钻型长期以来由于用成形砂轮刃磨成本过高,研究和应用均遇到很大的困难。Grinding wheel is generally line contact with the workpiece during milling. If the form of grinding wheel is suitable, it will be point grinding with the work piece. Then the required curve and curved face can be achieved by controlling the 'grinding points'. So the author puts forward a new principle of point forming grinding for rapid molding. As a special case of application, research and application meets difficulties respectively because of high cost of rapid molding sharpening on the tool flank of ellipsoid.
