Abstract

Cryogenic cooling is one way of improving tool wear resistance and efficiency of turning processes for hard-to-machine materials titanium-aluminum-vanadium and reaction bonded silicon nitride. Researchers at the University of Nebraska-Lincoln have developed a cryogenic cooling system capable of transporting cryogenically cooled liquid nitrogen from a tank to a reservoir located near the rear of the cutting insert. Tests conducted using the system revealed a great reduction in tool wear compared to dry machining and other cooling techniques. Lower temperatures reduced the chemical reaction between the work material and cutting tool, aside from preventing the softening of the insert material.
