摘     要
 在大力发展风力发电的大背景之下，风力发电机关键零件的加工制约着风力发电的有效效率，例如风力发电关键零件——叶縠零件的加工，由于其本身的质量和体积原因，加工往往有一些难度。
 本论文介绍了2.0MW风力发电机的关键零件——叶縠的生产工艺。生产工艺包括工艺规划，夹具设计和零件加工的数控编程。整个生产工艺将在保证实际加工质量的基础上选择最利于加工的路线。整个生产工艺都是利用软件进行虚拟设计。工艺规划和夹具设计在SolidWorks软件中进行，工艺规划就是对该铸造零件的加工面进行加工路线的编排，夹具设计即为进行上述加工时所需要的合理的夹具的设计。数控编程在SL软件下模拟。本文作者在查阅了许多相关文献资料并分析比较了国内外现有风力发电机叶縠零件的加工工艺的基础，确定了2.0MW风力发电机叶縠零件的加工工艺。

The Machining Of The Key Parts Of 2.0MW Wind Turbine
Abstract
 In the large background of developing wind power,the machining of the key components of wind turbines effect the efficiency of wind power,for example,the machining of the leaves-key componts of the wind power, As a result of its own quality and the size, it often have some difficulty in machining.
 This paper describes the key 2.0MW wind turbine components’ production process. The production process includs process planning, fixture design and NC machining program. The entire production process will select the most beneficial machining line based on ensure the quality of the actual processing. The entire production process is virtual designing by the software. The process planning and fixture design is designing in the SolidWorks . The processing is arranging for the machining line of the surfaces machined of the casting parts.In this paper, The fixture designing is designing the fixture which is needed in the machining .The NC programme is simulated in the SL.The author by accessing to a lot of comparative literature and analysis of existing wind turbine at home and abroad processing parts of the foundation, set the 2.0MW wind turbine components’ processing.
