Method and apparatus for electrochemical machining
First Claim
1. A method for electrochemically machining a work piece comprising the steps of:
- positioning an electrode near the work piece to form a gap between the electrode and the work piece;
providing a flow of an electrolyte through the gap;
forming a circuit to allow electrical power to flow through the electrode, the electrolyte in the gap, and the workpiece; and
generating a pulse of electrical power with a voltage less than or equal to 35 volts DC and a current greater than about 100 amperes and a pulse duration of less than about 10 microseconds to erode material from the work piece.

Abstract
An electrochemical machining apparatus and method for machining a workpiece. The apparatus provides a pulse of electric power, which is conducted from the workpiece, to an electrolyte flowing through a gap, and then to an electrode. Material is eroded from the workpiece when the pulse of electric power is applied, thus machining the workpiece. The apparatus includes a power supply to supply the electric power and a switching portion for producing the pulse by switching the electric power ON and OFF. The switching portion is capable of producing a pulse of electric power with a pulse duration of about 2 microseconds and a current of at least about 2800 amperes.
