ABSTRACT:
A controlled EDM apparatus comprises at least one electrode mounted in a base, a driver for positioning the base, a system for providing electrical energy to the electrode, a monitor for measuring the electrical discharge frequency of the electrode, and a controller responsive to the monitor for controlling either the driver or the energy providing system. The apparatus operates by measuring the electrical discharge frequency of the electrode and controlling at least the duration of machining in accordance with the frequency measured.
