<p>An electrical discharge machining apparatus (10) is provided with at least two work stations. A first servomotor (58) is mounted above the first and second work stations (12,14), and a second servomotor (60) mounted to the first servomotor (58) so as to be selectively positioned over either of the first and second work stations (12,14) by the first servomotor (58). The second servomotor (60) is capable of causing relative motion between an electrode and a workpiece fixture for a workpiece (44) in the first work station (12) when positioned over the first work station (12) and causing relative motion between an electrode and a workpiece fixture in the second work station (14) when positioned over the second work station (14). <IMAGE></p> |
