摘　　要：椭圆回转面因为具备特殊的光学性质而被广泛的应用,针对批量生产椭圆回转曲面精密模具的数控加工问题,给出了用平头铣刀三轴联动的加工方案和缜密的数学分析以及严格的数学证明,并给出了工具参数,加工行距以及加工数控进给量的整套计算模型,并用实例验证了方案的可行性和模型的可靠性,为此类精密椭圆回转面批量生产的模具的制造提供了全面的参考.The special optical property of the ellipse gyre surface has been used in a wide field. To produce the precision model of the ellipse gyre surface in batch with NC machining a machining scheme with flat-end milling cutter in 3-axis NC machining, the detailed mathematical analyses, the proving process, the machining parameter, the row space, and the integrated mathematical model in level and axis feed speed are presented. The feasibility and reliability of the model are proved with an example. This result provides abroad reference for producing ellipse gyre surface in a batch.
