END MILLING OF TI-48AL-2CR-2NB UNDER HIGH-FEED CONDITIONS
Journal Title: Journal of Machine Engineering - Year 2019, Vol 19, Issue 2
Abstract
Gamma titanium aluminides are fast developing materials and particularly in use for aerospace and automotive components. Due to the high cutting forces and raised cutting temperatures achieved during milling of this material, tool-wear is a crucial factor. Thus, increasing of the cutting speed leads to a significant rise of the cutting temperature. On the one hand, the implementation of innovative cooling strategies can reduce the heat flux in the cutting tool. On the other hand, analysing of the heat generation during the cutting process can lead to improved machining strategies. Previous research attempts assess microstructural and chip formation, as well as tool-wear in finish milling of this material. However, few have investigated the optimal cutting strategies in roughing and finishing of titanium aluminides. In this study, the milling operation under high feed rate should be investigated and the potential to improve chip removal rate and tool life should be determined.<br/><br/>
