Abstract

Abstract: In this paper， frequency is regarded as a new characteristic parameter to analyze vibration features. Firstly， the principle of vibration signal feature extraction was proposed， and the characteristic frequency function was obtained through the vibration feature extraction test of quick-point grinding. Then， the influence of different levels of technological parameters on grinding vibration under the machining or idle condition was analyzed. And the variation law of characteristic frequency was analyzed by comparing the contact and energy transfer relationship between the grinding wheel and workpiece. The results showed that the machining characteristic frequency is always smaller than the idle and the relative deviation of characteristic frequency decreases with the increase of the grinding wheel’s linear velocity， and increases with the increase of grinding depth and feed velocity. At the same time， the influence weight of each technological parameter on the characteristic frequency was compared， and the idea of improving the machining efficiency was put forward.

Key words: grinding vibration; characteristic frequency; technological parameter; quick-point grinding; relative deviation
