    Abstract
  • The surface integrity (surface topography, surface roughness, work hardening) of TB6 after side milling was studied based on the minimum data set. The results show that it's the feed engagement (fz) that influences the surface topography most and high fz may cause scale on the milled surface. fz is the main reason that influences the roughness of feed direction. The surface roughness (Ra) raised from 0.283 μm to 0.964 μm with fz increased from 0.06 mm/z to 0.12 mm/z. The milling parameters (vc,fz,ae) have no apparent influence on the roughness perpendicular to the feed direction while the flank wear (VB) influences it a lot. With the VB raised from 0 to 0.025 mm, the roughness perpendicular to the feed direction increased from 0.22 μm to 0.686 μm. There is no apparent work hardening or surface degenerating layer appeared during the side milling process of TB6.
