Abstract:Edge chipping is an important quality parameter in ultrasonic-vibration-assisted grinding (UVAG) of advanced ceramics. In this paper, the effects of cutting tool design, including three different tool angles at tool end surface and wall thickness of the cutting tool (core drills), and process variables on edge-chipping are investigated using a finite element analysis (FEA) model. Experiments are also conducted to verify the FEA predicted effects of process variables on edge-chipping for the three cutting tools.
