Edge-chipping reduction in rotary ultrasonic machining of ceramics: finite element analysis and experimental verification
نویسندگان
چکیده
Rotary ultrasonic machining (RUM) is one of the machining processes for advanced ceramics. Edge chipping (or chamfer), commonly observed in RUM of ceramic materials, not only compromises geometric accuracy but also possibly causes an increase in machining cost. In this paper, a three-dimensional finite element analysis (FEA) model is developed to study the effects of three parameters (cutting depth, support length, and pretightening load) on the maximum ∗ Corresponding author.
