Abstract: A preform includes an airfoil stub and a dovetail hub. The hub first undergoes electrochemical discharge machining to form a rough dovetail. The airfoil stub undergoes electrochemical machining to form an airfoil. The rough dovetail then undergoes electrochemical discharge machining to form a rough tang. The rough tang is finish machined to form a dovetail extending from the airfoil in a unitary rotor blade.
Abstract translation: 预成型件包括翼型坯料和燕尾形毂。 首先进行电化学放电加工以形成粗糙的燕尾榫。 翼型桩经历电化学加工以形成翼型。 然后粗糙的燕尾榫进行电化学放电加工以形成粗糙的柄脚。 粗糙的刀柄经过精加工，以形成从翼型在整体转子叶片中延伸的燕尾榫。
