In this report, the influence of the workpiece thickness upon the machining speed in ultrasonic machining was studied experimentally by measuring vibratory displacement of tool, machining speed, impulsive force and theoretically by using the theory of reflection and transmission of ultrasonic wave through a different solid medium. In consequence following results were obtained.
(1) When the workpiece thickness is large, machining speed decreases and becomes minimum when the thickness is equal to λ/4 (λ : wave length in the workpiece).
(2) It seems that the decrease in machining speed is due to the decrease in impulsive force.
(3) The rates of the decrease in machining speed and impulsive force are approximate to those of the theory of reflection and transmission of ultrasonic wave through a different solid medium.
