Sorotec-based milling calculator

Milling Speed, Feed, Axial & Radial Calculator

Uses Sorotec guide values for cutting speed and tooth feed by material and cutter diameter, then applies the entered spindle limits and cutting strategy.

Sorotec cutting data

Calculation mode

Conservative85% of table speed and tooth feed. BalancedUses the Sorotec table values directly. Aggressive110% of table speed and tooth feed, limited by spindle power.

Units Cutting-data profile Material Cutter diameter General material profile: 1–20 mm Number of teeth / flutes Cut type Custom cutting speed optional Usable flute length / LOC Axial recommendations are capped at this value.

Machine limits

Minimum spindle RPM Maximum spindle RPM Spindle power Available power factor

General material table

Supports 1–20 mm cutters. From 12–20 mm, the calculator holds the 12 mm tooth-feed value as a conservative starting point.
