Abstract
The objective of this research was to explore the impact of various cooling conditions on machinability, as potential alternatives to traditional cooling methods. To achieve this aim, a series of experiments were performed, where dry machining, minimum quantity lubrication (MQL), nanofluids, cryogenic (cryo) cooling, and hybrid cooling (cryo+nano MQL) methods were tested. Under distinct nanofluids conditions hBN(0.2 %) + graphene(0.2 %) performed well and overall cryo+nano MQL produced better result in terms of tool wear, microhardness, surface and chip morphology. The results demonstrated that the cooling effect of the Cryo-MQL regime, which maintains the cutting temperature at a tolerable level and preserves the lubricant performance of the MQL, is the cause of the lowest Vb value of 90 μm.
