9. Recommended Cutting Conditions
Parameters below are starting recommendations. Adjust based on machine rigidity, workpiece clamping, and coolant delivery.
| Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | ae (mm) |
|---|---|---|---|---|
| Carbon / Alloy Steel | 100-150 | 0.05-0.12 | 0.5-2.0 | 0.3-0.8 |
| Stainless Steel (303/304) | 70-100 | 0.04-0.10 | 0.5-1.5 | 0.2-0.6 |
| Aluminum Alloy (A5052/A6061) | 200-300 | 0.08-0.20 | 1.0-3.0 | 0.5-1.5 |
| Gray Cast Iron (FC250) | 80-120 | 0.06-0.15 | 0.5-2.0 | 0.3-0.8 |
10. Operating Guidelines
- Coolant: Use high-pressure coolant (≥70 bar) for steel and stainless steel. For aluminum, air blast or minimal quantity lubrication (MQL) is preferred to prevent built-up edge.
- Runout: Maintain toolholder runout ≤5 μm at 3×DC. Excessive runout reduces tool life and degrades surface finish.
- Engagement: For slotting, use full radial engagement (ae = DC) at reduced feed rates. For profiling, ae = 0.5-0.8×DC is optimal.
- Entry Strategy: Use ramp or helical entry. Direct plunge is permissible at reduced feed (50% of standard fz) with center-cutting capability.
- Speed/Feed: Start at the lower end of the recommended range and increase gradually while monitoring tool wear and surface finish.
- Tool Life Check: Inspect flank wear (VB) every 30 minutes. Replace when VB exceeds 0.15 mm or when surface finish degrades.
11. Toolholder Compatibility
ER16, ER20 precision collet chuck (≥3.5mm bore), hydraulic chuck, or milling chuck with runout ≤5μm at 3×DC.
| Holder Type | Specification | Recommended For |
