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.

Abstract
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.File in questo prodotto:
