Abstract

This paper elucidates the effect of Minimum Quantity Lubrication (MQL) system on the surface quality achieved during face milling of AISI 1045 steel components over the conventional flooded cooling system. This work was completed in a FANUC arrangement CNC Vertical Machining Centre (VMC) with three TiN coated carbide inserts of 0.4 mm nose radius adjusted into a face milling cutter of 25 mm in diameter. The machining parameters considered in this investigation are 4 number of passes, depth of cut, spindle speed, and feed rate. The experiments were planned based on Taguchi's L (3 ) 9 orthogonal array. The surface roughness of the machined components is measured using a surface roughness tester and subsequently, a mathematical model is developed for the average surface roughness values through regression analysis for both the machining conditions. The significance of the selected machining parameters and their levels of surface roughness are found by Analysis of Variance (ANOVA). The results revealed that machining under MQL condition provides better product surface quality than the machined product surface quality under flooded condition.
