Effect of minimum quantity lubrication on surface roughness in turninig AISI D6 steel

This study presents an investigation into the MQL (minimum quantity lubrication) and wet turning processes of AISI D6 work material with the objective of suggesting the experimental model in order to predict the surface roughness. Full factorial design were used for the experiment plan. In machining of parts, surface quality is one of the most specified customer requirements. The aim of this paper is to experimentally investigate the influence of cutting speed, feed rate and quantity of lubricant on surface roughness in turninig of AISI D6 with applying MQL. The optimization results indicated that MQL of 200 ml/h, cutting speed of 200m/min and a feed rate of 0.08 mm/rev is the best condition of machining to minimize surface roughness.
