Milling Cutter Feed Rate

Calculate optimal chip load, spindle RPM, table feed rate, material removal rate (MRR) and power for end milling, face milling and slotting. Built-in material database.

Table Feed Rate
1200 mm/min
10mm end mill, 4 flutes, chip load 0.1mm

Feed Rate vs Chip Load

Effect of chip load on table feed

Key Formulas
RPM = (SFM × 1000) / (π × D)
Feed Rate vf = f_z × Z × RPM
MRR = a_e × a_p × vf
Power ≈ (MRR × Kc) / 60 (kW)

Milling Guidelines

Chip Load Guide

Roughing: 0.1–0.3 mm/tooth

Finishing: 0.05–0.15 mm/tooth

Slotting: Reduce 50%

Radial Engagement

Full slot: a_e = D

Side milling: a_e ≤ 0.5D recommended

High a_e → lower chip load
