Ultrasonic-assisted grinding processing can effectively reduce the surface roughness and enhance the processing efficiency in the processing of hard and brittle materials. However, the most common ultrasonic assisted grinding is a type of contact ultrasonic grinding where the grinding tool directly contacts the workpiece, which means In the grinding of hard and brittle materials, therefore, the concept of the machining unit becomes particularly important because those materials are very sensitive to such defects. The machining unit can be classified into four domains as shown in Fig.3(3). Each domain is featured by the pre-existing defects or the defects generated throughGrinding of Hard and Brittle Materials ScienceDirect

Cutting force is one of the most important factors in the ultrasonically assisted grinding (UAG) of hard and brittle materials. Many theoretical and experimental studies show that UAG can effectively reduce cutting forces. The existing models for UAG mostly assume an ideal grinding wheel with abrasives in both the end and lateral faces to accomplish The grinding force is an important index during the grinding process, which affects the surface quality and other aspects after machining. However, the research on the grinding force of ceramic matrix composites assisted by two-dimensional ultrasonic vibration-assisted grinding is very weak.

Grinding is a finishing process used to improve surface finish, abrade hard materials, and tighten the tolerance on flat and cylindrical surfaces by removing a small amount of material. Grinding is one of the main methods of precision manufacturing and the process quality depends to a large extent on the experience of the operator In this study, ductile to brittle transition in ultra-micro-grinding (UMG) of hard brittle material is investigated. The characteristics of UMG process are studied, and differences between UMG and micro-grinding (MG) are investigated.
