AERIAL DISCHARGE MACHINING METHOD

摘要

PROBLEM TO BE SOLVED: To greatly improve the machining speed of aerial discharge machining. SOLUTION: A vibration device is provided for providing at least one of a machining electrode and a machined object with vibration having a vibration amplitude approximate to a small discharge gap length during aerial discharge machining and a vibration frequency approximate to a discharge frequency of a ultrasonic frequency to be generated or more. A dependent impulse type discharge machining power source is provided for supplying discharge pulses having a frequency equal to or more than the frequency of vibration to be provided by the vibration device depending on the condition of the discharge gap. Thus, aerial discharge machining can proceed while generating the discharge pulse in the state of being dependent on provided vibration. COPYRIGHT: (C)2004,JPO&NCIPI
