Minimum quantity lubrication (MQL) is a promising alternative to conventional flood cooling to substantially reduce lubricant cost and converse energy. Literature survey shows lack of investigation on the influence of MQL on the residual stress profile in grinding process. Residual stress is an important attribute of machined components for its notable influences on fatigue life, corrosion resistance, and fracture strength. This study has presented a thorough experimental investigation on grinding force, temperature, surface roughness, and residual stress behavior in grinding of AISI 1018 steel under MQL, dry, and flood cooling conditions.
