Abstract
The machining of hard to cut work materials produced lot of heat produced at the cutting zone resulted in generation of high cutting temperature at the tool-chip/tool-workpiece interface. Further, the high amount of tool wear (flank wear, crater wear), escalates the cutting forces, residual stresses as well as energy consumption and reduces the life of tool during turning process. To overcome these negative effects minimum quantity lubrication (MQL) as sustainable manufacturing technique has been largely used by researchers. High velocity mist droplets after penetration at the cutting zone, formed vapour blanket and give more effectual heat transfer than flood cooling. MQL process enhanced the turning performance in terms of low tool wear, excellent surface finish, and minimum cutting forces, lessen cutting temperature. This study, attempts to vitally evaluate the research scenario during turning of difficult-to-cut materials under environment friendly MQL technique.
