Abstract
In this paper efforts are made to refine the current cutting tool system for active error compensation, with the aid of ultrasonic vibration cutting technique. Two piezoelectric actuators are integrated in the cutting tool, one of which is for active error compensation and the other for ultrasonic vibration cutting. Principles of the active compensation for cutting error and the ultrasonic vibration cutting are first described. The characteristics of the piezoelectric actuators are experimentally studied and finally the integrated cutting tool is developed. Experimental cutting results have shown that the cutting tool developed is satisfactory in terms of improved roundness and surface roughness of machined workpieces.
