Need some pointers

[tech]

I have a chunk of aluminum structural C Channel that I need to "fillet" the outside corners.. 

Using a 3 Axxis Gantry mill.  As you can see the current tool paths generatated are trying to mill the face of the entire top surface of the channel. 

What would be the best way to isolate the milling operations to just the corner fillet areas?

Thank you!

I think I answered my own question by using "Split Face" on the geometry..

use flow and just pic the fillet

As Lenny said, use FLOW and pick the filet. Use a 1/2 or 3/8 BEM, climb mill,  .05 DOC x.05 WOC on your cut, 10K rpms, 667 SFM,  .0042 IPT, 85 FPM, with about 20 step-overs. Watch that first pass, you may need a roughing pass.
