Investigation of the microstructure change due to phase transition in nanosecond pulsed laser processing of diamond (2017)
Journal Article

Experiments and theory are employed to investigate the thermal damage induced by infra-red nanosecond pulses in atmospheric air into a boron-doped diamond target. Micro-Raman spectroscopy, Transmission Electron Microscopy (TEM) analysis and surface t...

New models for energy beam machining enable accurate generation of freeforms (2017)
Journal Article

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

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

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...

An approach on capturing the influence of the stochasticity of fibre distributions for modelling the variability of cutting forces in composite materials (2017)
Journal Article

The paper presents a novel model to evaluate the variation of orthogonal cutting forces for randomly distributed unidirectional fibres when cutting composite structures. The distribution analysis of fibre locations is first introduced into this topic...

Erosion mechanisms during abrasive waterjet machining: model microstructures and single particle experiments (2017)
Journal Article

The erosion mechanisms during abrasive waterjet (AWJ) machining have been examined for a variety of materials. However, no systematic study has considered the effect of the microstructure–property relationship on the erosion mechanisms in metals. In...

Towards understanding the cutting and fracture mechanism in ceramic matrix composites (2017)
Journal Article

Ceramic Matrix Composites (CMCs) are increasingly used for the manufacture of high-value parts for several industries such as the aerospace, nuclear and automotive. Nevertheless, their heterogenic, anisotropic and brittle nature make difficult to cha... Read More about Towards understanding the cutting and fracture mechanism in ceramic matrix composites.

Combustion flame spray of CoNiCrAlY & YSZ coatings (2017)
Journal Article

The properties of CoNiCrAlY and ∼7–8%YSZ layers, used as thermal barrier coatings (TBC) to protect hot gas paths of power generation and aerospace gas turbines, that have been deposited through the Combustion Flame Spray (CFS) process, are assessed a...

A novel cutting tool design to avoid surface damage in bone machining (2017)
Journal Article

With its anisotropic structure, bone machining occurs as shear/serrated cutting mechanisms at low values of uncut chip thickness while at high values it results in fracture cutting mechanisms which lead to significant tissues damages; hence, utilisin...

On a stochastically grain-discretised model for 2D/3D temperature mapping prediction in grinding (2017)
Journal Article

Excessive grinding heat might probably lead to unwanted heat damages of workpiece materials, most previous studies on grinding heat/temperature, however, assumed the wheel-workpiece contact zone as a moving band heat source, which might be not approp...
