A Study on the Effect of Hybrid Nanolubricant on Cutting Energy During Turning of Inconel 718 Under Minimum Quantity Lubricant Approach

A new type of technology that is evolving today is hybrid nanolubricants. The word hybrid can be considered to form a homogeneous phase of different materials that are a mixture of physical and chemical properties. Thus, hybrid nanolubricant refers to combination in base oil, two or more types of nanoparticles. Compared to traditional nanolubricants, hybrid nanolubricants have a great improvement in thermal or rheological properties. Application of hybrid nanolubricant in machining hard to cut alloy can be beneficial due to its excellent friction reducer and heat transfer properties. Lack of finding on benefits of the hybrid nanolubricants cutting fluids requires further exploration. Hence, in this work, the contrariety of several hybrid nanolubricant in terms of cutting energy and spindle power during turning of Inconel 718 was tested. Hybrid nanolubricant (Al2O3 + ZnO, 1:1) was found to be superior in reducing the cutting energy meanwhile hybrid nanolubricant (Al2O3 + SiO2, 2:1) managed to reduce the spindle power effectively as compared to other tested cooling condition. Hybrid nanolubricant is a potential cutting fluid for hard to cut alloy.
