Minimum quantity of lubrication (MQL) in machining is an established alternative to completely dry or flood lubricating system from the viewpoint of cost, ecology and human health issues. Hence, it is necessary to select proper MQL and cutting conditions in order to enhance machinability for a given work material. 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 H13 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.
