Speeds & Feeds
Determine optimal spindle speeds and feed rates to maximize tool life and material removal rates.
Reference Data
SFM and chipload values vary drastically based on the material being cut and the tooling material (Carbide vs. HSS).
Common Material SFM (Carbide Tooling)
| Material | SFM Range |
|---|---|
| Aluminum (6061) | 600 - 1200 |
| Low Carbon Steel (1018) | 300 - 500 |
| Stainless Steel (304) | 150 - 300 |
| Titanium (6Al-4V) | 80 - 150 |
Pro Tips
- Milling vs Drilling: For drilling operations, treat the tool as having 1 flute (if plunging) or 2 flutes depending on the specific drill geometry and manufacturer recommendations.
- Rigidity Matters: If your machine setup lacks rigidity, start at the lower end of the SFM range and reduce chipload by 20% to prevent chatter.
