广泛应用于汽轮机、发动机制造的叶片其表面属于高次自由曲面，如何提高其表面加工的精度和加工效率一直是叶片型面加工制造的难点。利用等残高法对不同类型叶片曲面的加工轨迹进行规划，并通过UG平台的二次开发模块和VC＋＋强大的编程功能，成功实现了叶片模型表面的法矢、曲率等关键信息的提取，并根据等残高法实现了曲面加工轨迹的规划。结果表明：通过基于UG平台开发的叶片曲面加工轨迹规划系统，可以实现叶片加工轨迹的基于不同加工参数的智能规划，并保证了曲面的加工精度。

Blades are widely used in manufacturing of steam turbine and engine,which surface belong to the high free curved surface.How to improve the surface's machining accuracy and machining efficiency have always been a difficult problem in blade surface's machining manufacturing.A plan was made for the machining path of different types of blade surface by using the method of equivalent scallop residual height,and through the secondary development module of UG platform and strong programming function of VC++,the information of blade surface's normal vector,curvature and other key information were successfully extracted.Moreover, the surface machining path planning was achieved according to the equivalent scallop residual height method.The result indicates that:through the blade surface machining path planning system based on UG platform development,it can achieve an intelligent planning of blade machining based on different machining parameters,and ensure the machining precision of curved surface.
