Cutting Data Finder
Displays recommended ranges for cutting speed and feed including start, minimum, and maximum values by material, operation, and tool.
How to use the result
The values are ranges for coated carbide tools from common machining handbooks and manufacturer catalogues. Start with the initial value and work towards the maximum while tool life, surface finish, and chip formation remain acceptable.
Feed per tooth and feed per revolution are scaled with diameter. The database is based on 10 mm; for substantially different diameters, the tool manufacturer catalogue is the better source.
For cutter engagement and chip thinning in milling, use the milling cutting-data tool.
Formulas
n = vc · 1000 / (π · D)vf = fz · z · n (milling), vf = f · n (turning, drilling)starting value = midpoint of the range from the material databasefz(D) = fz(10 mm) · (D / 10)^0,75, limited to between 0,15 and 3 times the base value Sources: Tabellenbuch Metall: reference values for cutting speed and feed; ISO 513: classification of the main machining material groups; Sandvik Coromant: Metal Cutting Technical Guide (material groups P, M, K, N, S, H)
