X4 Sfm Off In Contour Using Tapermill?

[Tony35]

is it just me or is the sfm off in contour using a tapermill

 

i have a 10 deg cutter 2 flute setup 800sfm S6112 feed @36.672ipm

 

in the tool tab it tells me the sfm is 400 all the other fields are correct checked it with a regular endmill all is good

 

anybody else seeing this

I wouldn't think you could calculate for a taper e-mill since the top of the e-mill would be a differant sfm than the tip (differnt dias). Sounds like it would be impossible.

[Tony35]

but you setup the tool off of the tip dia

 

it cut my sfm in half just was wondering if anybody else has seen this
