Abstract
The study is focused on the machined surfaced integrity of TB6 titanium alloy (Ti-10V-2Fe-3Al) after dry milling with carbide end mills of variable helix, variable pitch as well as conventional geometry. Roughness, residual stress, nanohardness, and microstructure alterations are investigated. The results show that not only the cutting speed and feed but also the geometric structure parameters of milling cutters have influence on the surface roughness and residual stress. Nanohardnesses exhibited inconsistent variation from the machined surface to bulk material. Plastic deformations and defects are detected in the machined surface. The deformation twins impact the anisotropy, the hardening effect, and the plasticity of TB6 titanium alloy machined surface.
