ELECTRO-DISCHARGE-MACHINE MACHINING CONDITION OPTIMIZATION METHOD

摘要

A discharge voltage detection unit (7) detects a discharge voltage and acquires an average discharge voltage in a predetermined time. An optimal machining condition calculation unit (8) calculates a discharge current which makes the average discharge voltage detected by the discharge voltage detection unit (7) identical to an average discharge voltage using a new machining liquid, and calculates the discharge time, halt time, and servo reference voltage in accordance with the calculated discharge current from the relational equation between the discharge current, discharge time, and halt time generating an optimal machining condition stored in the machining condition database storage unit (9). During machining, a servo (4) and a machining electrode (5) are controlled by the optimal machining condition via a servo control unit (6).
