Purposes of application of cutting fluid in machining:
- The main aim of the application of cutting fluid is to improve machinability through reduction of cutting forces and temperature, improvement by surface integrity, and enhancement of tool life.
- Cooling of the job and the tool to reduce the detrimental effects of cutting temperature on the job and the tool.
- Lubrication at the chip–tool interface and the tool flanks to reduce cutting forces and friction and thus the amount of heat generation.
- Cleaning the machining zone by washing away the chip – particles and debris.
- To form a solid lubricating layer under high pressure and temperature some extreme pressure additive (EPA) is deliberately added in a reasonable amount in the mineral oil or soluble oil.
