Cutting parameters effect on tin coated cbn cutting tools in hard turning of aisi 4140 steel

Abstract: 

Grinding method has a restricted use in the production of machine parts due to its long-processing time, high cost, and environmentally pollutant coolant liquid. The production of hardened materials via turning is an alternative to grinding operation. The generation by turning with little or no use of coolant liquid of surface properties similar to those obtained by grinding process decreases production time and cost. The present work aims at the determination of flank wear of cutting tool in turning of AISI 4140 hardened (53±1 HRC) steel materials with coated titanium nitride (TiN) cubic boron nitride (CBN) cutting tools under different cutting speeds and feed rates. Wear of cutting tool was determined through real-time monitoring and metallographic analysis. The best wear performance in turning of hardened AISI 4140 materials belonged to the cutting variables of 280 m/min, 0.04 mm/rpm coated cubic boron nitride.
