Vibroacoustic diagnostics of bidirectional end milling

Abstract

The hypothesis that high frequency vibration of a dynamic disk system is excited by a rotating roller is verified. The information content of the vibrational signal is determined. The characteristics of the vibrational signal are compared with the rotation characteristics and the machining precision.

“…With regard to rolling bearing, Pandey et al [8] focused on the mode shape of a curved surface and carried out damage detection, and the review by Tandon and Choudhury [9], which deals with vibroacoustic measurement techniques for rolling elements, are well known. In addition, Kozochkin et al studied the diagnosis using vibration measurement in the cutting process [10,11] and Sabirov et al studies the method for the end mill diagnosis [12].Further, Qiu et al investigated the diagnosis method using Wavelet ltering [13], Ban et al studied sounds generated from roller bearings for the diagnosis [14], Lei et al studied the diagnosis method using Kurtogram Method [15], Randall showed the tutorial of the vibration classi cation method [16], Zhao et al [17], and Immovilli et al [18] investigated the relationship between rotational speed and shaft radial load and vibration in the bearing system.…”
