Mathematical modelling of energy beam milling

Prof. John Billingham (University of Nottingham)
Friday September 23, 4pm – 5pm
Room: A2-002, University of Limerick (map)
Description: Mathematical modelling of energy beam milling In this talk I will describe three energy beam techniques (Abrasive Waterjet, Pulsed Laser Ablation and Focussed Ion Beam), that use very different physics to remove material from solid surfaces on the macro, micro and nano scales, respectively. After a brief discussion of some detailed physical modelling, I will describe how these three techniques can be unified into a single, simplified modelling framework that forms the basis of a practical method of designing beam paths to mill freeform surfaces.
