Abstract
The purposes of the present paper are to investigate the effects of ultrasonic vibration on machining accuracy of duralumin and to make clear the mechanisms for the improvement of machining accuracy in microdrilling. Ultrasonic vibration of 40 kHz considerably reduces the friction on the rake face, makes chips thinner and then decreases cutting forces. This decrease in cutting forces, especially the variation of the mean radial force, leads to the improvement of cutting accuracy, i. e., smaller hole oversize, a little better roundness at hole entrance, smaller displacement of hole center with ultrasonic vibration. The thin chip increases the velocity of chip flow, and results in better characteristics of chip disposal and less tendency of drill breakage.
