Annotation: We propose the design procedure of ultrasonic oscillatory system (UOS) with a working tool (WT) at one wavelength of ultrasonic vibrations in the material obtained according to the formula of the length of the UOS from WT. We received a 3D model of UOS with allowance for the WT size, calculated according to the formula proposed by the authors. The modal analysis of the calculated structure designed in the ANSYS.
