It is generally considered that the heat produced during the machining process is critical in terms of workpiece quality. Relatively high friction effects in machining cause heat generation that can lead to poor surface quality of a machined part. Coolant and lubrication therefore play decisive roles in machining. Cutting fluids are introduced in the machining zone to improve the tribological characteristics of machining processes and also to dissipate the heat generated, but they are partially effective within a narrow working range. In addition, they also create some techno-environmental problems. Solid lubricant assisted machining is a novel concept to control the machining zone temperature without polluting the environment. Solid lubricant, if employed properly, could control the machining zone temperature effectively by intensive removal of heat from the machining zone. Therefore, the aim of present study is to investigate the effect of molybdenum disulphide as solid lubricant in the zone of machining. Experiments were carried out to investigate the role of solid lubricant such as molybdenum disulphide on surface finish of the product in machining a AISI 4340 steel by coated carbide inserts of different tool geometry under different cutting conditions. Results indicate that the effectiveness of solid lubricant is substantial through the experimental domains.
