Experimental investigation of turning AISI D2 steel using sillimanite (Al₂SiO₅)

ABSTRACT

The global market’s need to decrease costs, minimize health and environmental risks, and achieve cleaner manufacturing has resulted in a growing interest toward hard turning in the manufacturing sector recently. Al₂SiO₅, Sillimanite is an abundantly available ceramic material with superior properties that is naturally available in the coastal areas of the districts of Odisha and Tamil Nadu, India. In this study, the machining performance while using sillimanite (Al₂SiO₅) sub-micron particles as MQL additives along with environmentally friendly rice bran oil (RBO) was studied while turning AISI D2. The maximum temperatures at the cutting zones are 371.8°C, 352.4°C & 341°C with SiO₂, Al₂O₃ and Al₂SiO₅ additives MQL, respectively. With Al₂SiO₅, the maximum flank wear is 49.9 µm which is significantly less than that of other additives SiO₂, Al₂O₃. Sillimanite, an environmentally friendly ceramic particle with superior mechanical properties when used as an additive for MQL provides greener solution for sustainable machining.
