In-process detection of tool wear have been attempted for adaptive control or unmanned operation of machine tools. This paper proposes a model based on the cutting data by the tool with flank wear land. In the model, stresses on flank wear land are related to the shear stress on the shear plane. The model and an energy method enabled to predict the cutting. forces and the cutting force ratios (axial force to tangential force, radial force to tangential force) with the increase of tool flank wear land in turning. It is clarified that a resolution of the increase of tool flank wear land by cutting force ratios is 0.025-0.035 mm/%. The analytical method is applied to set a criterion for sensing of tool wear by means of the cutting force ratios. The criterion set by analytical method is available to detect and control tool flank wear land.
