Introduction The excellent mechanical properties and outstanding strength-weight ratio have led to the successful application of Titanium alloys in biomechanical engineering and aerospace industry.
The high costs of machining Titanium alloys are mainly caused by the low productivity which resulted from two factors: the poor machinability and the unpredicted onset of chatters.
The poor machinability of Titanium alloys owing to the inherent properties of low thermal conductivity and high chemical reactivity, which adversely affect tool life, lead to premature tool failure and eventually cause the extremely low efficiency.
In an actual milling process, particularly for milling thin wall parts, continuous removal of material leads to the change in dynamics properties of the workpiece during the process.
It does not affect milling process because of its low energy.
