    Today I tested 50HRC 3 flutes end mill for aluminum. It was very very good. Cuts very good. It barely makes a sound.If you stop watching the machine, you cannot say it is cutting.

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: Worksurface 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
