7 Troubleshooting
Deburring process development is an iterative, learning task. The
following table is presented to assist in solving deburring
problems.
Symptom Cause Resolution
Burr Wear Hard work material Use better grade burr material add
coating (TiAlN)
Too heavy a cut Decrease width of cut/make multiple
passes
Feed rate is too slow Increase feed rate
Burr Breakage Too heavy a cut Decrease width of cut/make multiple
passes
Deflection at corner Climb mill/do not begin path at sharp
corner
Impacting part Decrease feed rate at contact/ enter part
at an angle
Unequal compliance Pivot bearing worn Replace pivot bearing,
