how to make this cut with a form tool?

I need to cut the chamfer on the bottom of this hook.  My chamfer tool has a top and bottom 45.  I can create this tool as a user defined tool.  But user defined tools can only be used with planner profile.  Has anyone figured out a good way to do something like this?

 

In this picture, I'm using a chamer tool with the shank drawn to represent the top 45.  My thought is to drive the outer dia of the tool and visually verify the cut using the shank position.  Any better ideas? 

 

Why can't I drive a form tool on an arc?  Or am I missing something.

 

Thanks for help

Bill

You can use an end mill and set the taper angle to -45 for example.

you can also use a Holemaking step drill.

Set base dia, 180 deg point and up .001" (or .01mm)

Then do 45 deg out

then do 45 deg in

Then do shank as another step or (NX10) as shank.

Ken,

can the step drill then be used with a fixed axis contour operation?

is this in NX9?

I've used them in FASC and VASC and planar mill

You may be forced to have a part surface (to drive tip of tool) and then drive surface.
