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. 4

SEM images of (a) poor and (b) best surface quality observed during turning of AISI 4340 steel. Figure 4 displays the SEM images of the poor and best surface texture quality attained by the interaction between AISI 4340 hardened steel and coated carbide tool using various cutting conditions. The SEM images show the status of machined surface in terms of surface voids, adhered oxides and chip particles, feed marks, material side flow, un-machined material, rough and smooth surface
