Abstract :This study is about turning AISI 1015 steel with coated carbide inserts in dry and MQL environments. In the experimental procedure built according to the full factorial experimental design, cutting parameters such as cutting speed (90,135 m/min), feed rate (0.2, 0.40 mm/rev) and cutting depth (0.1, 0.2 mm) on surface roughness, cutting force and cutting temperature were investigated. The experiments were carried out in two different environmental conditions, aiming to compare the machining performances in both environments and to determine the cutting parameters that make the biggest contribution to each output parameter. The main findings of the study are as follows: In turning operations performed under dry and MQL conditions, the worst surface quality (with surface roughness values of 2.509 µm and 2.114 µm respectively) was obtained at the lowest cutting speed, feed and depth of cut values. Increasing the cutting speed was manifested by the average 20.1% decrease in surface roughness for both environmental conditions. While cutting temperature and cutting force increased as the cutting speed increased at low feed rates, both decreased at high feed rates. Increasing the cutting depth caused an average 40% increase in cutting forces. Moreover, the surface roughness, cutting temperature, and cutting force data obtained under MQL conditions were on average 16.9%, 2%, and 29.8% lower than those obtained under dry conditions, respectively.
