Abstract
A system and method for electrochemically machining a work-piece contains a fixture capable of receiving a work-piece and securing the work-piece to the fixture. An electrolyte source is also provided. In addition, the system contains a rotary drive subassembly capable of receiving a portion of the work-piece therein, motion of the rotary drive assembly being determined by a received control signal, wherein frequency and amplitude of the control signal increases and decreases motion of the rotary drive subassembly, and wherein the control signal is a trapezoidal waveform.
