How ball nose parameters work
ADOC < 50% of diameter: Tool only cuts on part of its radius. Calculate effective cutting diameter (De) and use it for RPM and chip load — do not use actual D.
ADOC ≥ 50% of diameter: Use standard slotting speeds & feeds with actual D. Apply long-reach projection correction if gauge length exceeds 2.5×D.
De = 2×√(R²−(R−ADOC)²) · IPTadj = (D×IPTslot)/De · RPM = (SFM×3.82)/De · h = ae²/(8R)
