针对常规数控加工方法加工精密小模数蜗轮模具型腔，加工精确度低，齿形变形大，传动准确度低的问题，探讨了用Mastercam、UG软件进行蜗轮三维造型、四轴数控编程、数控线切割加工蜗轮模具型腔的工艺方法，给出了解决精密小模数齿轮模具加工新工艺，在工程上具有推广价值。

The distuibution of axial plane stubs and stub crossing points are non-uniform and quantity of them is not equal when the blade is made by using traditional design method of turbine. These are not benefit with calculating wood model and drawing. In this paper, to make blade wooden patterns is using blade mean camberline. This makes the wooden patterns meet the demand of the design and meet the shape of the runner blade. And this can agree with requirements of hydro and mechanical analysis and making the model of blade by using the numerical control machine. It has reference value to whole design of turbine.
