Optimum Design and Grinding Performance of Ultrasonic Hone-Lapping Tool with Fixed Abrasive Material

摘要

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 the paper, allowing for the advantages of finite element method in vibration analysis, vibration characteristics of hone-lapping segment were studied by means of FEA software. Through 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.
