TURN · CUTTING DATA
Turning feeds & speeds
Rough or finish turning data from the material group — spindle speed, feed, power, and the theoretical Ra your insert's nose radius can actually deliver.

Formulas used
n = 1000 · Vc / (π · D)Spindle speed at the current workpiece diameter.
Q = Vc · ap · fMaterial removal rate in cm³/min.
Pc = Q · kc / (60000 · η)Cutting power with specific cutting force kc and η = 0.8.
Ra = f² · 1000 / (32 · rε)Theoretical surface roughness from feed and insert nose radius.
