A dual material removal mechanism for clearing of obstructed holes via electrical discharge machining (2021)
Journal Article

Cooling hole blockages in gas turbine blades can occur during operation, detrimentally reducing performance and resulting in premature removal from service. Here, electrical discharge machining (EDM) is used to unblock fine holes, which have been obs...

Five simple tools for stochastic lattice creation (2021)
Journal Article

Lattices are increasingly used in engineering applications. They can reduce weight in aircraft components, increase the efficiency of heat exchangers and are used as medical implants. Typically a regular and graded lattice, where the unit cells are i... Read More about Five simple tools for stochastic lattice creation.

On the use of multiple layer thicknesses within laser powder bed fusion and the effect on mechanical properties (2021)
Journal Article

Laser Powder Bed fusion is capable of rapid production of parts, from conception, compared with traditional manufacturing methods. This said, the time taken to fabricate a single part can still be significant – typically many hours. Processing thicke...
