Surface roughness for TB6 titanium alloy impacts its performance significantly

 The effect on surface roughness and defects was studied through face milling parameters

dry milling and tool wear experiment. The results show that surface roughness for TB6 titanium alloy is mostly sensitive to the variation of feed per tooth

the next is the milling width

 then is the depth of milling and the last is the milling speed. The VB have a significant influence on surface roughness

 especially when VB is greater than 0.2mm

 the roughness values increases significantly as well as bringing on some scratches and grooves. Feed mark

 smeared and uplift material defects are observed on all machined surface samples. A large number of deposited material or pitting corrosion adhere to the worked surface during dry milling as well as burr formation increasing. Burr formation decreases with the increasing of milling speeds

while increases with the VB increasing. Wherefore

 TB6 titanium alloy is suitable for low milling speed with cooling lubrication during milling.
