Thermomechanical analysis induced by interrupted cutting of Ti6Al4V under several cooling strategies

Abstract

Cryogenic machining has mainly investigated in continuous cutting. Therefore, there is a lack of knowledge on the application of this technology to interrupted cutting, such as in milling. This study aims to investigate the thermomechanical phenomena in interrupted cutting of Ti6Al4V alloy under cryogenic, flood cooling and dry conditions. Due to the complexity of the thermomechanical analysis in milling, a special designed experimental setup has been developed through interrupted turning tests. This work highlights the influence of cryogenic flow rate and cutting time/non-cutting ratio on tool temperature. The obtained results can be extrapolated to milling operation.
