Cryogenic milling with internal delivery of liquid nitrogen is an effective way for improving the cutting performance and the environmental impact in machining of titanium. Physical experiments of down-milling of aerospace titanium have been conducted and a numerical model of the process has been developed, in order to model and predict the cutting forces. Combining the results of the numerical model and of a mechanistic cutting force model, it can be concluded that internal cryogenic cooling significantly changes the mechanics of the machining process, with respect to the dry conditions.
