A survey of methods for detecting metallic grinding burn

摘要

Grinding burn detection is essential for metallic components manufacturing because grinding burn not only reduces the functional performance and fatigue life but also affects the quality of precision grinding. Grinding burn occurs when the temperature of the workpiece in grinding zone rises above the tempering temperature of the material due to inappropriate grinding conditions, resulting in microstructural changes in the surface and may be accompanied with a reduction in strength, plasticity, and hardness, and may introduce unfavorable residual stresses. This work comprehensively introduces each of the existing metallic grinding burn detection methods and discusses their applications, advantages, and limitations. Moreover, the trends of developing methods for detecting metallic grinding burn are also presented. (C) 2018 Elsevier Ltd. All rights reserved.
