Common Milling Problems and Solutions

Excessive Chatter: Vibration and sound are excessive when the tool engages the workpiece.

Possible Solutions:

Increase your feed
Reduce your cutting forces by reducing speed and/or feed or axial and/or radial depth of cut
Increase your system′s rigidity by changing over to a stub length end mill or improving your workpiece fixturing
Change geometry - use an end mill with variable flute spacing or a small circular margin

Poor surface finish
Surface Finish: Work surface looks uneven and feels rough.

Possible Solutions:

Increase system rigidity
Increase speed
Reduce feed
Change to higher helix geometry
Change to an end mill with more flutes
Excessive Wear of End Mill

Excessive Wear of End Mill: Tool is wearing at cutting edges causing poor performance.

Possible Solutions:

Reduce Speed - A 50% reduction in speed will almost double the tool life
Increase/decrease feed - A feed rate that is too light will cause excess rubbing
Change geometry of the tool - Number of flutes, helix angle, length of cut
Change material grade and/or add a coating.
