Abstract: Titanium and titanium alloys are difficult to machine treat in normal conditions. This paper examines the surface roughness of Ti6Al4V alloy after machining in conventional machines with various tool geometries, cutting speeds and lubrication/cooling conditions. The surface roughness of biocompatible Ti6Al4V is important when this titanium alloy is used for cell growth on human implants. The results reported in this paper may provide a guideline on adhesion, orientation and growth of fibroblast for the Ti6Al4V titanium alloy.

Keywords: titanium alloys; biocompatible Ti6Al4V; surface roughness; tool geometries; cutting speeds; lubrication; cooling; cell growth; human implants; bioengineering; adhesion; orientation; fibroblast; machining.
