Investigators from Lappeenranta University of Technology Target Industrial Engineering (Chatter Detection in Turning Processes Using Coherence of Acceleration and Audio Signals)
By a News Reporter-Staff News Editor at Journal of Engineering -- Data detailed on Industrial Engineering have been presented. According to news reporting originating in Lappeenranta, Finland, by VerticalNews journalists, research stated, "Chatter is an unfavorable phenomenon in turning operation causing poor surface quality. Active chatter elimination methods require the chatter to be detected before the control reacts."
The news reporters obtained a quote from the research from the Lappeenranta University of Technology, "In this paper, a chatter detection method based on a coherence function of the acceleration of the tool in the x direction and an audio signal is proposed. The method was experimentally tested on longitudinal turning of a stock bar and facing of a hollow bar. The results show that the proposed method detects the chatter in an early stage and allows correcting control actions before the chatter influences the surface quality of the workpiece."
According to the news reporters, the research concluded: "The method is applicable both to facing and longitudinal turning."
