The concept of applying and studying the performance of new coolants is always the interest of researchers to reduce the cost and environmental impacts with improved machining performance. This study examines the impacts of factors like spindle speed, feed rate, and depth of cut under dry, wet, and minimum quantity lubrication (MQL) condition on the surface roughness (Ra) during end milling of EN31 in a CNC vertical milling machine. The experimental strategy is based on Taguchi's L9 orthogonal array technique, with three factors and three levels for each variable, and an analysis is done to determine the influence of each factor on surface roughness. Experimental surface roughness values are used to construct the contour plots, and the impacts of the parameter changes are investigated. In comparison to dry and wet conditions, the surface roughness is lower in MQL conditions. For MQL conditions, rice bran oil is applied as lubricant. ANOVA is used to determine factor's influences on surface roughness. It is found that the spindle speed is the most influencing factor for surface roughness. The MQL is considered to be one of the best alternatives for wet machining and is very effective. [ABSTRACT FROM AUTHOR] |
