An electrical discharge machining (EDM) apparatus includes a single workpiece fixture for holding a workpiece and a plurality of machining heads for machining different features into the workpiece. For example, a first machining head is arranged to machine a first feature into the workpiece, and a second machining head is arranged to machine a second feature into the workpiece. Each machining head is connected to a separate control system so as to operate independently.
