摘要:
A method of forming integrally bladed rotors for gas turbines is described. The method includes drilling in a workpiece material recesses defining flow passages and rotor blades, performing a coarse milling step to refine surfaces of the rotor blades, and filling the recesses between the rotor blades with a damping material, thus encasing the rotor blades in the damping material. The method further includes performing a finishing milling step to remove the damping material and the workpiece material on surfaces of the rotor blades, while maximizing a damping effect of the damping material on the rotor blades. To maximize the damping effect, the finishing milling tool moves along a path that preferentially mills one surface of a blade while the other surface is in contact with the damping material.
摘要(中):
描述了一种用于燃气轮机形成一体叶片转子的方法。 该方法包括在工件材料中钻出限定流动通道和转子叶片的凹槽,执行粗磨步骤以细化转子叶片的表面,以及用阻尼材料填充转子叶片之间的凹部,从而将转子叶片包围在阻尼 材料。 该方法还包括进行精加工步骤以在转子叶片的表面上移除阻尼材料和工件材料,同时最大化阻尼材料在转子叶片上的阻尼作用。 为了最大化阻尼效果,精加工铣刀沿着优先铣削刀片的一个表面的路径移动,而另一个表面与阻尼材料接触。
