摘要: Abstract Trends of machining hardened steel are increasing in manufacturing industry due to its advantages surface quality over grinding and other finishing process. One the major benefits hard turning is attaining better with high dimensional accuracy. However, large amount heat generation during affects performance. The application lubricants used control temperature. use conventional cutting fluids have become more problematic terms health environmental pollution. Minimization fluid will lead cost-effectiveness overall machining. Therefore, aim this research work investigate role minimum quantity lubrication (MQL) technique on AISI 4340 CBN tools. speed, feed rate, nose radius workpiece hardness selected as process parameters investigations. mathematical model roughness developed using second order regression analysis. Analysis Variance (ANOVA) results show that MQL helps improving compared dry wet conditions turning.
