Ti6Al4V is classified as a difficult-to-machine material; consequently, CNC machining operations require the use of carbide or coated cutting tools. During processing, its poor thermal conductivity often leads to accelerated tool wear, while its high chemical reactivity can compromise surface quality. Nevertheless, Ti6Al4V (TC4) remains the most widely utilized α+β dual-phase titanium alloy currently available. Renowned for its high strength, low density, exceptional corrosion resistance, and excellent biocompatibility, it is extensively employed across the aerospace, medical implant, and high-end manufacturing sectors.
