Comparison of dry and cryogenic machining on chip formation and coefficient of friction in turning AISI 4340 alloy steel

Application of cutting fluid that provides both coolant and lubrication properties in manufacturing operations such as turning, milling, grinding and other processes has been proven to improve the machining output in many aspects. In cryogenic machining, liquid nitrogen (LN2) is used as cutting flu...
