Minimum Quantity Lubrication (MQL) is known to perform better than conventional flood cooling in machining. However, no studies on MQL using alternative cutting fluids with the chosen work-tool material combination, are reported in the literature. Thus, the aim of this study was to evaluate the effect of MQL using alternative cutting fluids on tool wear. The objectives were; to identify suitable alternative cutting fluids that can be used with the MQL method, and to study the tool wear for different alternatives. Alternative cutting fluids were identified using a literature review. Then a set of simple turning operations using carbide coated tools and AISI D2 steel work-pieces were performed with the MQL method using three identified alternative fluids. Trials were also carried out with dry cutting, conventional flood cooling with emulsion oils and MQL method using emulsion oils. Tool wear in each treatment was measured and graphically analysed to compare the performance of the cooling methods. Coconut oil, sun flower oil and waste cooking oil were identified as the alternatives for conventional cutting fluids. Coconut oil and sun flower oil performed the best while waste cooking oil was the worst. Further experiments are need with different combinations of cutting tool and work-piece material to generalise the findings.
