The normal amplitude distribution of a 2 dimensionally extended radiation surface of an ultrasonic vibration tool is made uniform by a modal vibration control method which employs straight horns called 'Wave-Trapping Horns'. After numerically finding the tool shape which provides an in-phase longitudinal mode at the surface, the mode control is carried out. The displacement amplitude uniformity between the minimum and the maximum values along the surface is successfully increased from 75% to 85%.
