Seminar: Modelling of laser assisted machining of titanium

AMPAM Seminar Series

Event Details

Date: Friday, 27 June 2014
Venue: 49-502
Speaker: Yao Xi
Event Description: 
Laser assisted machining is a promising machining technology to machine difficult to machine materials such as titanium alloys. It is difficult to reveal the mechanism behind the laser assisted machining solely through experimental works due to its complex thermo-mechanical features, therefore, computer models were applied to investigate this process. In this seminar, Yao will present titanium alloys machining models which were developed using the traditional finite element method and the smoothed-particle hydrodynamics method. The comparisons between the simulation results and the experimental results will be presented and the chip formation mechanism of titanium alloys during meachining process will be discussed. The adiabatic shear band theory and the initiation and propagation theory were implanted to explain the formation of the saw-tooth chips in this study. A discussion about the relationship between the unique saw-tooth chip morphology and the cutting force vibration during machining of titanium alloys will be included as well. Yao Xi graduated from the Beijing University of Chemical Technology, China in 2010 with a Bachelor of Engineering majoring in electrical engineering. He commenced his PhD studies at the University of Queensland under the supervision of A/Prof Matthew Dargusch and Dr Gui Wang in January 2011.
