Cause
Be aware of the power curve as the machine may lose efficiency if the rpm
is too low.
The power requirements in milling vary with the:
- Amount of metal to removed
- Average chip thickness
- Cutter geometry
- Cutting speed.
Solution
- Go from close to coarse pitch, i.e. fewer teeth
- A positive cutter is more power efficient than a negative cutter
- Reduce cutting speed before table feed
- Use a smaller cutter and make several passes
- Reduce depth of cut, ap
