Description

Abstract: During metal cutting, the employed cutting tool experiences thermo-mechanical loads that causes wear at the interacting surfaces, hence, limiting the tool life. The speed of cutting and active feed of tool dominates the wear magnitude; hence, these factors were considered in the developed analytical tool wear model. Considering the high heat generation and consequent temperature rising in the cutting zone, the effect of temperature was included in the developed model. Finite element analysis of the metal cutting was conducted to achieve the worn face data (i.e., contact pressure) that was used in the analytical model. The experimental results of the orthogonal cutting of AISI1045 steel using cemented carbide cutting tool showed a close agreement of the proposed tool wear model and predicted tool life with reasonable accuracy, hence validating the models.
