Experimental Study of the Turning Elements Effect on the Power Spectrum Density of Turning Vibration of Cutting Tool

Abstract:

By means of the QLVC-ZSA1 vibration signals analyzer and an acceleration sensor, three experimental schemes, (1) different spindle speed and (2) different feed rate for the first half and the second half of the same feed length, and (3) three successive feeds under the same turning parameters, were designed to study quantitatively the vibration responses of the cutting tool in the turning process by the numerically controlled lathe. The study indicated that (1) with the increase in the spindle speed and feed rate, the maximum self-power spectral density of the tool vibration also increased, while the corresponding vibration frequency decreased; (2) with the increase of the material removal during the turning, the maximum self-power spectral density of the tool vibration displayed a increasing trend and its average value varies from 5.0 to 9.0 , and the frequency of the maximum tool vibration energy concentrated at the about 3750Hz.
