Thermal aspects in the face grinding of ceramics

To meet the increasing demand on the quality and cost of precision structural components, extensive studies on high efficiency and precision machining of ceramic materials, including face grinding, have been conducted over the past few years. In the present study, experiments of face grinding two typical ceramics were carried out to study thermal aspects at the wheel–workpiece contact zone. According to the experimental results and the comparison of theoretical and measured temperature profiles, the temperature characteristics and mechanism of energy partition in the face grinding of ceramic materials were discussed. The temperature rise in the workpiece and energy partition during the grinding process were found to be directly related to the machining parameters and the mechanism of material removal.
