Speed and Feed Chart
When machining materials with an unfavorable length-to-diameter ratio, coarse thread pitches, or hard materials, you may need to use more radial depth passes than indicated on the speed and feed chart.
Micro End Milling Parameters
| Ø (mm) | Material | Speed (RPM) | Feed per Tooth (mm) | Axial DOC (mm) | Surface Speed (m/min) |
|---|---|---|---|---|---|
| 0.1 | Aluminum 6061 | 40,000 | 0.002 | 0.03 | 12.6 |
| 0.1 | Stainless 316L | 28,000 | 0.0015 | 0.02 | 8.8 |
| 0.2 | Titanium Ti6Al4V | 24,000 | 0.003 | 0.04 | 15.1 |
| 0.3 | Hardened Steel 50HRC | 18,000 | 0.004 | 0.06 | 17.0 |
| 0.5 | Carbon Fiber | 30,000 | 0.008 | 0.10 | 47.1 |
Critical Formula:
RPM = (Surface Speed × 1000) / (π × Tool Diameter)
Feed Rate (mm/min) = RPM × Flutes × Feed per Tooth
Micro Drilling Parameters
| Ø (mm) | Material | Speed (RPM) | Feed per Rev (mm) | Max Depth (L/D) | Peak Temp (°C) |
|---|---|---|---|---|---|
| 0.15 | Oxygen-Free Copper | 45,000 | 0.006 | 8:1 | <120 |
| 0.20 | Inconel 718 | 15,000 | 0.003 | 5:1 | 650 |
| 0.25 | FR-4 PCB | 38,000 | 0.008 | 12:1 | <180 |
| 0.30 | Titanium Grade 5 | 20,000 | 0.005 | 7:1 | 420 |
| 0.50 | P20 Tool Steel | 12,000 | 0.012 | 10:1 | 580 |
Optimization Highlights
| Parameter | Industry Default | SDF Enhanced | Benefit |
|---|---|---|---|
| SS 316L Feed | 0.001 mm/tooth | 0.0015 mm/tooth | Chip evacuation ↑37% |
| Titanium Speed | 20,000 RPM | 24,000 RPM | Work hardening prevention |
| CFRP DOC | 0.08 mm | 0.10 mm | Delamination risk ↓43% |
