Schnittkraft berechnen

Milling force formula and how to use it

Cutting force depends on the material-specific cutting force coefficient (kc), axial depth of cut (ap), feed per tooth (fz), and radial engagement (ae). This calculator gives the tangential force and resulting spindle torque.

• Cutting force F = kc × ap × fz × ae / 1000 (Newtons)
• Spindle torque T = F × r / 1000 (Nm), where r ≈ tool radius in mm
• kc values: steel ≈ 2000-2500 N/mm², stainless ≈ 2500-3000, aluminium ≈ 700-900, titanium ≈ 1400-1800

How to use this Milling Cutting Force & Torque Calculator

Enter your material's specific cutting force (kc), depth of cut, feed per tooth, and radial engagement. Use the calculated force and torque to verify your spindle can handle the load and to size workholding fixtures.
