Axial depth of cut ap
Feed per insert fz
Cutting speed (m/min) Vc Table feed, mm/min
Max chip thickness hex (may be adjusted)
Effective diameter Deff
Radial chip thinning / Milling with the periphery of the cutter
If the width of cut (ae) is less than half the effective diameter of the cutter, D eff,
and the periphery of the cutter is engaged, the table feed should be increased. Table feed, mm/min
For applications meeting these conditions, enter the width of cut ae
