Investigation of the Ultrasonic Cutting Mechanism
What happens in the ultrasonic cutting process is that a cavity is formed in the material to be machined, emulating the shape of the tool tip. The spent material is withdrawn along the surface perpendicular to the plane of vibration of the tool or to the direction of the applied static force. The rate of disintegration of the material can be characterized by two variables: the linear rate of change of the depth of the cavity and the performance, i.e., the volume of material removed per unit time. In the drilling of holes of constant area the performance is proportional to the machining speed, P = Sv, where S is the area of the hole and v is the machining speed.
