Study and Comparison of Lubricity of Green and Commercial Cutting Fluid Using Tool-Chip Tribometer

A lubricant is a substance introduced between surfaces in mutual contact to reduce friction, which ultimately reduces the heat generated when the surfaces move. Liquid lubricant, designed specifically for metalworking processes, such as turning, drilling, milling etc. is known as cutting fluids (CF)...

description	A lubricant is a substance introduced between surfaces in mutual contact to reduce friction, which ultimately reduces the heat generated when the surfaces move. Liquid lubricant, designed specifically for metalworking processes, such as turning, drilling, milling etc. is known as cutting fluids (CF). Cutting fluid is a blend or combination of oil, emulsifier and additives, mostly derived from chemicals or petroleum products.

Properties of these cutting fluids are dependent on the nature of the base-oil, nature of surfactants and the properties of water used to make the CF.
