Cutting tool is one of the critical elements in the machining process. Tool wear describes the gradual failure of cutting tools due to regular operation Flank wear of cutting tools is often selected as the tool life criterion because it determines the diametric accuracy of machining, its stability and reliability. Tool wear in cutting process is produced by the contact and relative sliding between the cutting tool and the workpiece, and between the cutting tool and the chip under the extreme conditions of cutting area. In this work is developed the first model for predicting tool wear based on experimentally measured values and multiple regression analysis method and four factors (spindle speed, feed rate, depth of cut and workpiece hardness) at three level orthogonal experiment, during turning hardened 42CrMo4 steel using TiAlN/TiN multi-layer coated carbide inserts.
