PROBLEM TO BE SOLVED: To provide an electric discharge machining for a work such as an aircraft engine part with some machined characteristic shapes. SOLUTION: An electrical discharge machining (EDM) device (10) comprises a plurality of machining heads (22-32), at least one EDM control system (76, 78) and a plurality of programmable servo drive devices (84, 86). Each of the programmable servo drive devices (84, 86) is connected with each one of the EDM control systems (76, 78) and a plurality of the machining heads (22-32) respectively. The programmable servo drive devices (84, 86) receive velocity commands from the EDM control systems (76, 78) and provide control signals controlling positioning of electrodes to each of a plurality of the machining heads (22-32).
