Abstract
The present research focuses on machinability assessment of AISI 304 material under the integrated effect of MQL and hybrid texture tools in turning operation. AISI 304 poses significant machining challenges because of poor heat transfer and more strength. To enhance tool performance, novel dual micro-texture tools integrated of continuous wavy and circular dimple textures were developed and the developed tool performance was evaluated under conditions. The results revealed that the synergistic impact of MQL with textured tools outperformed both wet and dry environments by significantly reducing cutting temperature (T), flank wear (T(f)) and rake wear (T(r)), while also improving surface finish (R(a)). The textures acted as micro-reservoirs for lubricant retention and promoted better chip flow at the cutting zone, contributing to improved tribological performance at the tool-chip interface. It was observed that the MQL condition reduced the 'T', 'Ra','Tf' and 'Tr' to 18%, 25%, 31% and 42% respectively when compared to dry cutting environment. Whereas it was 14%, 13%, 15% and 25% when compared to wet condition. The synergistic benefits of MQL and hybrid textured tools meets the functional improvement with eco-friendliness requirement while cutting AISI 304.
