Investigation into Engineering Ceramics Grinding Mechanism and the Influential Factors of the Grinding Force

Abstract

The grinding force is a key parameter in the grinding process, which is closely associated with the grinding mechanism of engineering ceramics, microstructure and properties of ceramic materials, and the selection of grinding parameters. Meanwhile, it is also a key indicator to assess the grindability of a material. The grinding force is a crucial parameter to reflect the grinding process, which is closely related with microstructure and properties of the grounded material, grinding parameters, grinding wheel characteristics and material removal mechanism. In this paper, from the perspective of material removal mechanism in ceramic grinding model and the grinding process of engineering ceramics, the ceramics grinding process was analyzed and the formation of grinding force was explored. With the analysis of characteristics of the grinding force, from the aspect of influential factors of the grinding force, impacts of the performance of ceramic materials, grinding direction, grinding wheel velocity, workpiece velocity, grinding depth, particle size of grinding wheel, grinding wheel wearing, the grinding fluid, the rigidity of machine tool and process system and other factors on the grinding force were analyzed, thus providing further knowledge and development of ceramics grinding.
