This paper investigates the effects of tool vibration and wear surface deterioration on scattering in flank wear of carbide cutting tools. When turning 0.46%C carbon steel with a carbide tool at relatively high speeds, the amplitude of vibration just under the cutting edge, which gives the minimum of wear rate on the flank wear land, appears. A hypothesis for explaining variations in the wear rate is proposed, in which changes of temperature and stress on the wear land and fatigue deterioration of the wear surface brings about the scattering, being induced by vibration between the tool and the work material. The vibration includes cases in which the wear land completely separates from the machined surface. Numerical analysis and special impact and/or thermal fatigue experiments prove that the hypothesis, in conjunction with a wear characteristic equation proposed elsewhere, holds qualitatively.
