Fig. 9From: Experimental investigation of surface roughness, flank wear, chip morphology and cost estimation during machining of hardened AISI 4340 steel with coated carbide insertChip thickness at different cutting speeds. Figure 9 presents some aspects of chips obtained in the present investigation under various cutting conditions during turning of AISI 4340 high strength low alloy steel using coated carbide tool. As the feed reduced and the cutting speed increased, a reduction of chip thickness is occurred (see, Fig. 9) and produced chips of three categories, i.e. long helical washer type broken chips, long and snarled unbroken chips and ribbon type chipsBack to article page
