Abstract
Milling is a widely employed material removal process for different materials. It is characterized by high material removal rate. Machining
leads to high friction between tool and workpiece, and can result in high temperatures, impairing the dimensional accuracy and the surface
quality of products. Application of conventional cutting fluid may not effectively control the heat generation in milling. Besides, cutting
fluids are a major source of pollution. Solid lubricant assisted machining is an environmental friendly clean technology for desirable control
of cutting temperature. The present work investigates the role of solid lubricant assisted machining with graphite and molybdenum
disulphide lubricants on surface quality, cutting forces and specific energy while machining AISI 1045 steel using cutting tools of different
tool geometry (radial rake angle and nose radius). The performance of solid lubricant assisted machining has been studied in comparison with
that of wet machining. The results indicate that there is a considerable improvement in the process performance with solid lubricant assisted
machining as compared to that of machining with cutting fluids.
