Abstract:

Vibration assisted machining is a technique to apply high frequency vibration between tool and workpiece in addition to original cutting motion. In this study, the effect of two dimensional vibration assistance on the cutting performance of glass and metallic materials is investigated. Specifically, this presentation includes three sections: (1) The vibration assisted micro-milling of BK-7 optical glass is investigated. (2) Two dimensional vibration assistance on the attenuation of high frequency regenerative chatter in the micro milling of aluminum is studied. (3) An efficient algorithm based on 2D finite element method is proposed to characterize the coupled axial-torsional dynamics of micro drill due to the warping effect.

Introduction of the speaker:

Jin Xiaoliang, Assistant Professor, Mechanical and Aerospace Engineering, Oklahoma State University, USA. He obtained B.S. degree on Mechanical engineering from Beihang University in 2004 and PhD on the same object from University of British Columbia in 2012. Later he become a Postdoctoral Fellow in Department of Mechanical Engineering of UBC. And he held the assistant position in School of Mechanical and Aerospace Engineering, Oklahoma State University since he finished the Postdoctoral work. He has published several important papers and is focusing on the research of Micro-Machining, Nano-Machining, Machining of Aerospace Materials, Cutting Mechanics and Dynamics, Precision Control of Machine Tools at Oklahoma State University.
