| Abstract | Ultrasonic assisted grinding processes promise high potential for economical machining of brittle hard materials and improved workpiece qualities. Especially in machining of high performance ceramics as well as ceramic matrix composites (CMC) a significant decrease of process forces and increased material removal rates can be achieved. In previous publications the fundamental effect mechanisms related to ultrasonic assistance in grinding processes were described. However, implicit knowledge about the influence of the tool specifications and geometry on the maximum achievable ultrasonic amplitude is lacking. Furthermore, knowledge about the behavior of the high-frequency tool motions during tool engagement could simplify the design of ultrasonic assisted grinding processes. A targeted utilization of ultrasonic effects can be result in lower process forces, less tool wear and shorter machining times which lead consequently to more sustainable processes. The presented work provides results of the interactions of tool design, tool contact conditions and workpiece in the ultrasonic assisted machining of ceramics with mounted points.
