Specific Grinding Energy Causing Thermal Damage in Helicopter Gear Steel

Thermal damage (burn) in carburized and hardened helicopter gear steel caused by grinding was investigated. Excessive grinding temperatures cause grinding burn and result in excessive scrap or reduced fatigue life. Vasco X2M gear steel, used in helicopters, was prepared and heat-treated by a researc...

description Thermal damage (burn) in carburized and hardened helicopter gear steel caused by grinding was investigated. Excessive grinding temperatures cause grinding burn and result in excessive scrap or reduced fatigue life. Vasco X2M gear steel, used in helicopters, was prepared and heat-treated by a research partner, U.S Army. Grinding tests were conducted on this steel. Nital etching was used to detect grinding burn. Model was established to predict onset of thermal damage for Vasco X2M steel based on specific grinding energy determined from grinding force measurements. The model was compared to results published for other steels. A control strategy is suggested based on the model to avoid grinding burn.
