High Feed end mill configuration


I encounter a wired bug.

When I create High Feed Mill:

Tip Dia: 25,000 mm

Flutes: 3

Stick Out: 62,3

Corner Radius: 1mm

Ball Nose: False F

lute length 2,5mm

Lead Angel: 21

Shank Dia 25mmm

Helix Angel: 0

Shoulder Len 60mm

Tappered: False

Shoulder Dia 25mm

Results for Slotting WOC is:

DOC: 1,5mm

WOC 19,7889

DOC: 1mm WOC: 25 mmm

DOC: 0,9 WOC 24,9

DOC: 0,5 WOC 24,7321

I think with 0,1 DOC it should be between 14-16mm WOC. Maybe I put something wrong? Regards, Jakub WaƂkowski

2.5mm flute length seems very high for a HFM.

For Feed mills the flute length is the maximum cutting depth.

Also what material are you calculating it for?

You are not going to see exactly the same values as suggested by your manufacturer because there is a lot of variance between different tools.

From the little that I can see on the screenshot it looks OK.

Best regards.
