9. Recommended Cutting Conditions
Starting parameters for 15.00mm diameter, 4-flute endmill. Adjust based on machine rigidity, workpiece clamping, and coolant conditions.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Axial Depth ap (mm) |
|---|---|---|---|
| Carbon Steel (≤ 0.45% C) | 70-140 | 0.04-0.10 | 0.1-0.5 |
| Alloy Steel (≤ 900 N/mm²) | 63-119 | 0.04-0.10 | 0.1-0.5 |
| Stainless Steel (Austenitic) | 56-105 | 0.03-0.09 | 0.1-0.5 |
| Cast Iron (GG/GGG) | 77-147 | 0.04-0.10 | 0.1-0.5 |
Note: Values are starting recommendations. Actual parameters may vary based on machine condition, setup rigidity, and coolant delivery. Always perform test cuts when machining new materials.
10. Operating Guidelines
- Speed & Feed: Start at lower speed range with fine feeds. Increase speed gradually while monitoring surface finish quality.
- Depth of Cut: Axial depth (ap) 0.1-0.4mm for finishing. Radial depth (ae) 5-12% of cutter diameter.
- Coolant: High-pressure coolant or precision oil mist for optimal heat dissipation and surface finish.
- Runout: Keep tool runout below 0.008mm. Precision collet or hydraulic chuck recommended.
- Ramp Entry: Helical entry at 1-2° ramp angle. Avoid direct plunging into workpiece.
- Chip Evacuation: Ensure positive chip evacuation to prevent recutting and surface damage.
