Abstract
A machining process includes providing a cutting tool having a rake face and a flank face; bringing the cutting tool into contact with a metal alloy work piece to form a chip by penetrating the cutting tool into the workpiece; and introducing a nanofluid into a vicinity of the penetration to remove heat and, in some instances, customize the finished surface. The nanofluid includes a mixture of a cryo-liquid and nanoparticles having a maximum size of approximately 0.1 nanometers to approximately 100 nanometers.
