Understanding Feed Rate
Feed Rate Formula
Feed Rate (IPM) = RPM × Flutes × Chip Load
- IPM = Inches Per Minute
- Chip load varies by material
- Adjust for depth of cut
Factors Affecting Feed Rate
- Material hardness: Harder = slower
- Cutter size: Larger = faster
- Depth of cut: Deeper = slower
- Tool sharpness: Dull = slower
Signs of Incorrect Feed
- Too fast: Burning, rough cuts, tool breakage
- Too slow: Burning, glazing, poor finish
- Listen for smooth cutting sound
- Watch for smoke or burning smell
Optimization Tips
- Start conservative, increase gradually
- Use sharp tools
- Multiple shallow passes better than one deep
- Adjust for grain direction
- Consider machine rigidity
