Typical Value
Description
Spindle Speed
1,000 – 3,000 RPM
Lower speeds reduce heat buildup.
Spindle Power
≥ 5 kW
Higher power ensures stable cutting forces.
Feed Rate
0.05 – 0.2 mm/tooth
Adjust based on tool diameter and rigidity.
Cutting Depth
0.5 – 3 mm
Shallower cuts (<1 mm) for fine finishes.
Cutting Width
30–50% of tool diameter
Prevents tool deflection.
Machining Accuracy
±0.005 – ±0.025 mm
Depends on machine rigidity and tool wear.
Surface Roughness
Ra 0.8 – 3.2 µm
Finer finishes require slower feeds/polishing.
Tool Type
Carbide or diamond-coated end mills
Sharp, high-helix tools reduce heat.
Tool Diameter
3–12 mm
Smaller tools for intricate features.
Coolant Type
Air blast or minimal mist
Avoid excessive coolant to prevent thermal shock.
Chip Load
0.05–0.15 mm/chip
Ensures efficient material removal.
Ramp Angle
≤ 5°
Reduces tool stress during plunging.
Stepover
30–60% of tool diameter
Balance between efficiency and finish.
