P. Lequien: PhD Abstract

Milling of a titanium alloy Ti-6Al-4V with a cryogenic support

First publications of cryogenic assistance in machining appears at the end of the 20th century. The machining thermal problems predominate in the characterization of tools, materials or processes. Many studies seek to demonstrate the relationship between the rising temperature and cutting operations. The idea of the cryogenic machining assistance is to cool down the workpiece or the tool during material removal phases. The aim of this thesis is to characterize phenomena induced by liquid nitrogen applied during milling process.
