jfet.13.1.13761 The Effectiveness of Various Cutting Fluids on the Surface Roughness of AISI 1045 Steel During Turning Operation Using Minimum Quantity Lubrication System Milon D. Selvam N.M. Sivaram Journal on Future Engineering and Technology 2230–7184 13 1 36 43 10.26634/jfet.13.1.13761 AISI 1045, Machining, Servocut 'S', Palm Oil, Peanut Oil, Minimum Quantity Lubrication System, Taguchi This paper elucidates the effect of mineral oil based cutting fluid such as Servocut 'S' grade oil emulsified with water and used edible vegetable oil based cutting fluids, such as Palm Oil and Peanut Oil emulsified with water on the surface quality of AISI 1045 cylindrical steel components. The turning operation is carried out with three TiN coated carbide inserts of different nose radius on AISI 1045 steel using Minimum Quantity Lubrication system. The machining parameters, namely spindle speed, feed rate, depth of cut, tool nose radius and cutting fluids are decided for the lead of trials. The 5 trials are designed based on Taguchi's L (3 ) orthogonal array. The surface roughness of the turned samples is measured 27 with a surface roughness analyzer and in this manner; a scientific model representing the average surface roughness is created through regression examination. The results revealed that the surface quality of the turned samples using vegetable based cutting fluids are equivalence with the components machined using mineral oil based cutting fluid.
