9. Recommended Cutting Conditions

Starting parameters for 10.00mm diameter, 4-flute endmill. Adjust based on machine rigidity, workpiece clamping, and coolant conditions.

Workpiece MaterialCutting Speed Vc (m/min)Feed per Tooth fz (mm)Axial Depth ap (mm)
Carbon Steel (≤ 0.45% C)100-1800.08-0.180.3-1.0
Alloy Steel (≤ 900 N/mm²)90-1530.08-0.180.3-1.0
Stainless Steel (Austenitic)80-1350.06-0.150.3-1.0
Cast Iron (GG/GGG)110-1890.08-0.180.3-1.0

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: Optimize based on material hardness. Softer materials allow higher speeds; harder materials require reduced speeds.
  • Depth of Cut: Axial depth (ap) can be up to 1.5× diameter for roughing. For finishing, reduce to 0.3-0.8× diameter.
  • Coolant: Flood coolant recommended for steel and cast iron. Air blast or MQL for aluminum.
  • Runout: Keep tool runout below 0.015mm for balanced performance.
  • Ramp Entry: Helical entry at 2-3° ramp angle. Plunge only if center-cutting design is confirmed.
  • Chip Evacuation: Critical for deep slotting. Use through-spindle coolant when available.
