Titanium alloys are widely used for aerospace thin–walled parts such as compressor or turbine blades, frames, etc. The main motivation for application of these alloys is their outstanding metallurgical properties such as: hot hardness, high corrosion resistance and wear-resistance. However, in production, titanium alloys are categorized as difficult-to-cut materials. In this study, the surface integrity of thin-walled titanium parts which are produced by milling operations are evaluated against different cutting conditions such as cutting speeds and immersions. Microstructural analysis is performed and cutting forces are measured using a table dynamometer. Finally the optimum cutting conditions for the process are proposed.
