Abstract: The present paper is a contribution to the investigation of the vibration frequencies accompanying saw-tooth chip formation in the case of hard turning. The study concerns the universal turn Gallic 20 machining with coated carbide of tempered AISI 4340 steel with a Rockwell C hardness of 47 HRC. The main idea in this paper deals with the establishment of a direct relationship between chip morphology simultaneously with amplitude of acceleration component signals derived from acquisition at high frequency and with the width of facets detected on a workpiece machined surface.
