ABSTRACT:
A laser guided discharge machining apparatus includes a vacuum chamber in which pressure can be reduced to 3000 Pa or below and in which a workpiece is accommodated as well as a discharge electrode that emits charged particles. A laser beam is used to guide the discharge to thereby enable parts of the workpiece to be discharge machined which are not in a direct line from the discharge electrode.
