Özet

It is known that performing the roller burnishing (RB) process in dry or wet conditions has negative effects on process outputs and sustainability. Therefore, the importance of using the minimum quantity lubrication (MQL) method is increasing. In this study, nano-molybdenum disulfide (MoS2) doped nanofluid-assisted MQL (MoS2-NMQL), nano-graphene (nGP) doped nanofluid-assisted MQL (nGP-NMQL) and MoS2/nGP doped hybrid nanofluid-assisted MQL (HNMQL) burnishing conditions were used for the first time in the RB of AISI H11 steel and RB performance was investigated in terms of burnishing power and surface roughness improvement. Then, optimization was performed to minimize power consumption and maximize surface roughness improvement using NSGA-II and CoCoSo methods. Compared to the dry condition, using the HNMQL condition reduced the burnishing power and increased the surface roughness by 2.8% and 16.3%, respectively. Using the HNMQL condition, a burnishing speed value of 250 rpm, feed values between 0.075-0.084 mm/rev and depth of burnishing values between 0.391-0.412 mm provided optimum results in terms of power consumption and surface roughness improvement.
