Abstract: Because of its high machining efficiency and good machining quality, ultrasonic hone-lapping with fixed abrasive material is regarded as a good method of cylindrical machining for hard-brittle materials. But it is relatively difficult to design the acoustic system in ultrasonic hone-lapping tool due to the complicated shape of hone-lapping segment. In this paper, allowing for the advantages of finite element method in vibration analysis, the vibration characteristics of hone-lapping segment were studied by means of Finite Element Analysis (FEA) software. Through the modal analysis and harmonic analysis, the optimum installation position of hone-lapping oilstone and the optimal exciting frequency were confirmed. Finally, contrast experiments of ultrasonic and conventional hone-lapping were carried out to validate the grinding performance of the tool designed in the paper.

Keywords: finite element analysis; FEA; grinding performance; optimum design; ultrasonic hone-lapping; fixed abrasive material; cylindrical grinding; brittle materials; hard materials; vibration analysis.
