Project Title: Optimising tool performance in the cryogenic machining of light materials.

Academic Supervisor: Dr Tom Slatter

AMRC Supervisor: Dr Chris Taylor

Sponsor: Sandvik Coromant

I have a passion for learning new things and understanding the impact of human knowledge on shaping the world in which we live. This passion led me down the path of becoming a mechanical engineer. After I graduated with a first class Master’s degree in 2014, I had two successful years investigating and optimising the parameters influencing precision grinding within a senior role with the Knowledge Transfer Partnership programme.

I am now in the first year of my EngD, at the IDC of machining science, working on a project that will shape the modern factory. The project involves enabling the industry to remove water and oil from the manufacturing process, positively impacting the environment and the machine operator’s health. 

Cryogenic machining is an emerging technology that uses cryogenic (or near cryogenic) fluid as a coolant rather than the traditional oil-water emulsions. Environmental, economic and health benefits have been reported when making the change.   

As cryogenic machining is an emerging topic there is a paucity of cryogenic specific tools, with little understanding of those that are available. The research findings will directly influence the future direction of solid tool design for cryogenic machining products within Sandvik Coromant.

The research focuses on the machining of light ‘hard to machine’ materials, such as titanium, across a range of machining processes including drilling and end milling. Key determinants of the research include chip formation and evacuation in addition to tool geometry and tool coatings applied.
