Abstract:
raditionally,
machining titanium alloys only can be achieved with low cutting speed, massive cooling lubricant and at lower feed
rates. Since the application of Minimum Quantity Lubricant is employed in recent machining activities and the
development of cutting tools allow the machining of titanium alloys at higher speed within green machining
approach. The full factorial design of experiment approach has been performed in turning titanium alloy (Ti6Al4V)
and shows that Cutting Speed is the dominant element in the cutting parameters that controlling the tool life and
followed by feed rates and Depth of Cut. Further analysis indicates the MQL application outrun the tool life in Dry
cutting condition. The machined surface roughness is more sensitive to the tool wear and feed rates rather than
cutting speed or cooling strategies.
