A study on tool performance to determine the optimal cutting conditions for dry end milling of an aeroengine material: Ti-6242S

The present study deals with a study on the dry end millingof the titanium alloy Ti-6242S. From an extensive experimental work involving numerical simulations, the performance of the off-centre ball end millingalloyed carbide tool (W-(Ti/Ta/Nb)C-Co) has been analysed. Optimal cutting conditions have been found among cutting speed, Material Removal Rate (MRR) and tool life. Also, it has been established that tool failure modes, tool wearmechanisms and tool performance change for each optimal combination of cutting conditions. The chip morphology, the tool-chip contact length, and all tribological parameters (temperature, pressure, etc.) involved for each optimal cutting condition have been evaluated.
