Study on Minimum Quantity Lubricant Conditions to Improve the Surface Roughness in Hard Turning of SKD 61 Alloy Steel

In this research, Taguchi method was applied to find the optimal values of minimum quantity lubricant MQL condition in hard turning of SKD 61 with consideration of reduced surface roughness. The performance characteristics of MQL parameters cutting fluid type, pressure and fluid flow were studied by using a L9 array, the signal to noise ratios and analysis of variance ANOVA . In result of the present study, the lubricant and the pressure of MQL condition are the most influential factors which give statistic significant effect on machined surfaces. In addition, the optimal condition of the MQL mode to reduce the roughness was also presented.
