ELECTROCHEMICAL MACHINING METHOD AND APPARATUS

摘要

An electrochemical machining system and method includes at least one tube arranged in a first fixture, a second fixture arranged adjacent to the first fixture, the second fixture adapted for supporting a workpiece relative to the tube, a translation mechanism which causes relative movement between the first fixture and the second fixture, a power supply which supplies a current to the workpiece and the tube, and a control unit which controls the power supply to alternately apply a forward current and a zero current (C₀) to the workpiece and the tube for a total time interval (t_t) wherein deplation of the workpiece occurs and bubbles are separated from the tube. This may be followed by a reverse current (C_R) or voltage to the workpiece and the tube for a second time interval (J_R), wherein deplation of the workpiece occurs.
