Abstract
An ultrasonic machining method comprises the steps of causing a machining solution to readily produce a gas in the machining solution, supplying the machining solution around a workpiece to be machined, and producing an ultrasonic vibration to carry out an ultrasonic machining operation, wherein the gas is produced during the machining operation so that a machined surface of the workpiece is prevented from being degraded by the occurrence of cavitation. An ultrasonic machining apparatus comprise a heater for heating the machining solution or a DC power source for electrolyzing the machining solution.
