Abstract : Ti-6Al-4V alloy is an excellent material used in aerospace industries due to its high strength to weight ratio and
their excellent corrosion resistance. However, because of its low thermal conductivity and high chemical reactivity, Ti-6Al-4V
alloy is considered as a difficult-to-machine material. It is well known that tool wear has a strong relationship with the cutting
forces and a sound knowledge about correlation between cutting forces variation and tool wear propagation is important to
analyze and optimize the machining parameters of titanium alloy. In the present study, finish-milling of Ti-6Al-4V alloy with
tungsten carbide tools under dry cutting conditions is experimentally investigated. The current study is to analyze the cutting
force variation and tool wear rate for optimized parameters during finish milling of Ti- 6Al-4V alloy. The finish milling
parameters selected for the experiments are cutting speed 20 to 50 m/min. The depth of cut is kept constant at 1.0 mm and then
feed rates are varied from 0.02 to 0.08 mm/rev. Single insert based cutting tool is used for these experiments. From the
experimental study it can be seen that 30m/min is the optimum cutting speed, when compared to other cutting speeds. From
the study, flank wear of VB= 0.11 mm at a cutting time of 30 min is considered as an optimum tool life for the optimized
cutting speed.
