Journal Article
Axinte, D. A., Billingham, J., & Guillerna, A. B. (in press). New models for energy beam machining enable accurate generation of freeforms. Science Advances, 3(9), Article e1701201. https://doi.org/10.1126/sciadv.1701201

We demonstrate that, despite differences in their nature, many energy beam controlled-depth machining processes (e.g. waterjet, pulsed laser, focused ion beam) can be modelled using the same mathematical framework – a partial differential evolution e...

Waterjet and laser etching: the nonlinear inverse problem (2017)
Journal Article
Bilbao Guillerna, A., Axinte, D. A., Billingham, J., & Cadot, G. (2017). Waterjet and laser etching: the nonlinear inverse problem. Royal Society Open Science, 4(161031), https://doi.org/10.1098/rsos.161031

In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional... Read More about Waterjet and laser etching: the nonlinear inverse problem.

A study of surface swelling caused by graphitisation during pulsed laser ablation of carbon allotrope with high content of sp ³ bounds (2017)
Journal Article
Cadot, G., Billingham, J., & Axinte, D. A. (in press). A study of surface swelling caused by graphitisation during pulsed laser ablation of carbon allotrope with high content of sp ³ bounds. Journal of Physics D: Applied Physics, 50(24), https://doi.org/10.1088/1361-6463/aa70fe

Experiments and theory are employed to investigate the laser ablation of boron doped diamond and tetrahedral amorphous carbon using nanosecond pulses. For a single pulse at low values of fluence, the laser induces a swelling of the surface due to gra...
