Can not get 3D contour down last section

[Anonymous]

I am trying to do a 3d contour down the inside of a funnel, I can not get it past the bottom of the funnel.  I have entry points from the top all the way to the very bottom of the funnel

My first op is running a 3/8 drill all the way through

1/2" rougher for the interior body of the funnel

1/4 ball mill for the contouring,

contour down the initial vertical section

then down the 45 degree slope

I need it to contour from the slope to the bore of the funnel so there is a very smooth transition

I cant figure out what I am missing to get it to go down the bore of the funnel.

Any ideas? 

Thanks!  Ill try to post up screen shot in a bit

Just a hunch: set the Bottom Height minus the radius of the tool from the bottom of the geometry. So in this case since you are using a 1/4" ball mill, select the bottom edge of your funnel face as the Bottom and input -.125 for the offset field.

I changed the machining boundary to silhouette and tool containment to inside and it made the path correct all the way down the interior of the funnel spout.

I think I had changed it away from that earlier due to it attempting to machine the outside of the funnel.

Thanks!!!!
