Abstract
An ultrasonic processing method is disclosed wherein during the processing time interval the motional amplitude of the resonating horn and thereby the power to the workpiece is reduced. The reduction in motional amplitude may be in response to a process condition such as a change in dimension of the workpiece or a sharp rise in the power curve, or it may be in response to the lapse of a predetermined time.
