Abstract
An apparatus and method for machining apertures into a conductive workpiece is disclosed. The apparatus has a tank capable of holding a dielectric fluid, and a fixture for holding the workpiece in the tank. An electric discharge machine with an electrode, a power supply connected to the electrode that produces machining pulses for electric discharge machining through the workpiece, and a controller for regulating the power supply and electrode position is also part of the apparatus. Finally, the apparatus has a pressure transducer connected to the fixture, and a process controller in communication with the electric discharge machine controller and pressure transducer.
