Grinding thermal damages, also known as grinding burns, will shorten the fatigue life of critical, dynamically loaded components and can lead to severe failures. Grinding burns occur when the energy from grinding produces too much heat. Grinding burn decreases hardness and causes tensile residual stress. The grinding process has many parameters
