Ultrasonic-Vibration Hard Cutting Force Analysis with the Finite Element Method
Ultrasonic-vibration hard cutting (UVHC) is a advanced technology, where high- frequency vibration is superimposed on the movement of the cutting tool. Compared to conventional turning (CT), this technique allows significant improvements in processing hard-to-cut materials, by producing a noticeable decrease in cutting forces and a superior surface finish. The paper presents a finite-element model of both CT and UVHC. Stresses produced in workpiece and cutting forces acting on the cutting tool in UVHC are studied, and the influence of cutting parameters, such as cutting speed and cutting depth on cutting force are investigated.
