Coolant and lubrication in machining

Abstract

This chapter is focused on coolant and lubrication in machining. The cutting fluids are known to aid the machining process by providing cooling action and lubrication. The functions, properties, classification, and guidelines for selection and application of the cutting fluids have been discussed in detail in this chapter. One of the key aspects of machining is the tribology of the tool-chip and tool-workpiece interfaces where the contact conditions are severe and the temperatures are very high. The contact stresses and the temperature estimates at these interfaces have been presented which could help in selecting an effective cooling/lubrication Cutting fluids strategy during metal cutting. The recent advances in field of cutting fluid application in machining, such as dry machining, minimum quantity lubrication (MQL), and cryogenic machining, have also been covered.
