Evidence Basis
Based on empirical high-feed roughing data from Seco Tools (tooling manufacturer) application testing. These are recommended starting parameters for Ti-6Al-4V; actual values depend on machine rigidity, coolant pressure, and toolpath.
Engineering Interpretation (titanium.blog)
(titanium.blog) High-feed milling trades radial engagement for high feed per tooth, keeping the tool in a shallow, chip-thinning engagement that moves heat out of the cut — well suited to titanium’s low thermal conductivity. Larger cutters run slightly slower SFM but sustain higher MRR. Treat as starting points, not absolutes.
