“…The reported findings state reduction in surface roughness under different machining environments like wet [5,6], MQL [7,8], hybrid machining [9], cooling air and minimum quantity lubrication (CAMQL) [10] and liquid nitrogen (LN2) [11]. Further the beneficial effects of machining environment in inducing lesser tensile or more compressive residual stresses have been also reported for wet [5,6] and cryogenic [12] environments, to mention a few. Podgorkov and Godlevski around 1990s proposed a new pollution-free cutting technique with water vapour as coolant and lubricant in machining, and further works on it reported decrease in surface roughness of various work materials like C45 steel [13], ANSI 304 stainless steel [14] and Titanium alloy (Ti6Al-4V) [15].…”

Abstract:This paper investigates the effect of material removal rate (MRR) and mainly machining environment on resultant surface integrity in high-speed machining (HSM) of Inconel 718. For this high-speed turning is carried out for three different cutting speeds, feedrates and depth of cut under dry, flood coolant and water vapour machining environments. The results show that flood cooling is ineffective in high-speed machining. Water vapours acts as a coolant and lubricant, and hence is highly effective in lowering surface roughness and surface damages in machining. However at very high material removal rates, dry machining seems to be an economical option. Under all the environments the residual stresses were found to be compressive in nature at all MRR levels. Keeping in view green manufacturing, good productivity and better quality, it is suggested that machining of Inconel 718 under water vapour environment is an ideal approach.
