Recommended Cutting Conditions
The following parameters are starting recommendations for stable machining centers with adequate rigidity. Adjust based on machine condition, workpiece fixturing, and coolant delivery.
| Parameter | Carbon Steel | Aluminum Alloy |
|---|---|---|
| Cutting Speed (Vc) | 50 m/min | 150 m/min |
| Spindle Speed (n) | 34,810 rpm | 104,432 rpm |
| Feed per Tooth (fz) | 0.008 mm/z | 0.008 mm/z |
| Table Feed (Vf) | 0.56 mm/min | 1.67 mm/min |
| Axial Depth (ap) | 0.0216 mm | 0.0216 mm |
| Radial Depth (ae) | 0.0108 mm | 0.0108 mm |
| Coolant | Emulsion or synthetic | Air blast or mist |
Operating Guidelines
- Runout Control: Maintain total indicated runout (TIR) below 0.005 mm (0.0002") at the tool point. Excessive runout dramatically reduces tool life in micro-diameter endmills.
- Rigidity: Use the shortest possible overhang and high-quality collet chucks or hydraulic holders. Minimize tool protrusion to avoid chatter and deflection.
- Ramping: When entering the workpiece, use a helical ramp entry with a maximum angle of 2° to minimize shock loading on the delicate cutting edges.
- Pecking: For deep pocketing or drilling operations, employ a peck cycle with 1×D peck depth and 0.2×D retract to ensure chip evacuation.
- Coolant: For steel machining, flood coolant is recommended to control thermal cycling. For aluminum, air blast or minimum quantity lubrication (MQL) prevents chip welding.
- Speed/Feed Adjustment: Reduce cutting speed by 20% for interrupted cuts or thin-wall sections. Increase feed rate by 10% for full slotting to maintain chip thickness.
- Tool Inspection: Inspect cutting edges under magnification after every 30 minutes of cutting time. Early detection of micro-chipping prevents catastrophic failure.
