Which way would you attack this contour?

[honeybunches]

Trying to help someone out real quick and figures things would not go as planned.  The area in teal needs machined.  The radius of that dished area is .130 and I would like to just use a 1/4" ballnose for this and make a couple rounds.  I cannot find any surface path that will give me what I need.  Ideally I would like to start at the outside and gently ramp or helix in and walk around the bottom towards. 

 

That little notch is no issue and will be deleted from the design so I am hoping and I can just drive past it like it was not there?

I'd use contour ramp no lead in/out with finish pass at full depth.

Surface Flowline with spiral cutter movement has worked for me in cases like this..

Could you do what JLW said but with 6.50 mm ball mill? Not knowing tolerances or finish may be able to do it in 2 cuts.

wireframe -> 2d swept will do exactly what you want.

flowline...copy surface and untrim and get rid of that notch...

Create the exact 2d contour you want the tool center to follow 1" above the part and then use surface project.

I'm guessing you got your tax stamp approved?
