From: Experimental investigation of surface roughness, flank wear, chip morphology and cost estimation during machining of hardened AISI 4340 steel with coated carbide insert

Fig. 12

Growth of flank wear vs. machining time at optimum conditions in hard turning. Figure 12 illustrates the growth of tool wear with machining time until the end of useful life of a tool as determined by flank wear width under optimum cutting conditions, considering wear criterion of VB up to 0.3 mm
