Abstract: An ECM method involves the use of a thin hollow electrode assembly that carries the electrolyte within and that is advanced relatively to the workpiece. The small profile of the electrode results in a minimal removal of metal in forming the desired rotor or stator shape. The electrode profile allows significant power consumption reduction or increased machining speed for a given rate of power input. The electrode can be a unitary ring shape or can be made of segments that are placed adjacent each other so that a continuous shape is cut. Not all the lobes of the stator or rotor have to be cut in the same pass. Electrode segments can be used to sequentially provide the desired lobe count in separate passes. The lobe shapes in the electrode can be slanted to get the desired rotor or stator pitch or they can be aligned with the workpiece axis.
Abstract translation: ECM方法涉及使用将电解质携带并相对于工件前进的薄中空电极组件。 电极的小轮廓导致在形成期望的转子或定子形状时金属的最小去除。 对于给定的功率输入速率，电极轮廓可以显着降低功耗或提高加工速度。 电极可以是整体环形的，或者可以由彼此相邻放置的片段制成，从而切割连续的形状。 不是所有的定子或转子的叶片必须以相同的通道切割。 电极段可用于在单独的通路中顺序提供所需的波瓣数。 电极中的波瓣形状可以倾斜以获得所需的转子或定子节距，或者它们可以与工件轴线对准。
