Project Title: Machining distortion analysis and control during hybrid machining processes


Academic Supervisor: Dr Hassan Ghadbeigi

AMRC Supervisor: Dr Sabino Ayvar-Soberanis

When a part is made by additive manufacturing (a.k.a. 3D printing) it may need to be machined in order to meet tight geometric requirements. The problem is that during additive manufacturing, especially of metals, a concentrated heat source like a laser is used, which causes rapid melting and solidification. This causes stress in the part so it can distort when it is machined. The aim of my research is to understand how these stresses are formed and control how parts deform when they are machined.


I decided to do a PhD because I wanted to further my understanding of engineering, gain new skills and because I really enjoy manufacturing engineering research. The PhD should give me even better opportunities when I return to industry.


Despite almost going into geophysics I was probably destined to be an engineer as I have a habit of giving myself little projects that involve making or tinkering with things. My latest project has been teaching myself leather work.
