Edge-chipping reduction in rotary ultrasonic machining of ceramics: finite element analysis and experimental verification
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 d...
متن کاملStudy on Edge Chipping in Rotary Ultrasonic Machining of Ceramics: An Integration of Designed Experiments and Finite Element Method Analysis
Rotary ultrasonic machining (RUM) is a relatively low cost and environmentally benign process for machining of advanced ceramics. Much effort has been made to theoretically and experimentally investigate material removal rate, surface roughness, and tool wear in RUM. However, there is no report on systematic study of edge chipping in RUM drilling of ceramics. This paper presents the results of ...
متن کاملAn Experimental Investigation on Surface Roughness and Edge Chipping in Micro Ultrasonic Machining
Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...

متن کاملRotary ultrasonic machining of ceramics: design of experiments
Rotary ultrasonic machining is one of the nontraditional machining processes for advanced ceramics. Currently available in literature are publications on theoretical and experimental studies on material removal rates in rotary ultrasonic machining. However, there is no report on the systematic study of the cutting force in rotary ultrasonic machining. Furthermore, the effects of some process pa...
