Tribological Considerations of Cutting Fluids in Machining Environment: A Review

The paper presents a review to highlight the tribological aspects of cutting fluids in machining environment. In this study, different machining processes viz. turning, grinding, drilling and milling have been considered with a special focus on grinding process. The cutting fluids are primarily used as coolants and lubricants in the various machining processes. Different cutting fluids and the health hazards associated with their use have also been represented in this research article. The paper also highlights the role of work materials and the cutting tool materials from tribology point of view. The literature revealed that the development of biocompatible cutting fluids, recycling of cutting fluids, cutting fluids for high temperature tribological applications, studying the wetability characteristics with addition of nanoparticles, etc. can be taken up as study in order to enhance the tribological properties of the cutting fluids.
