A machining process capable of increasing material removal rates when machining Titanium, Ceramic and its alloys. The process includes heating a portion of a workpiece with a laser beam, cryogenically cooling a cutting tool with a cryogenic fluid without flowing the cryogenic fluid onto the workpiece, and machining the heated portion of the workpiece with the cutting tool. The cryogenic fluid is circulated around the cutting tool to achieve a temperature differential between the workpiece and the cutting tool that is capable of improving removal rates and extending tool life at cutting speeds of, for example, above 100 m/min.
