Need Help!- NX7

[Rumm64]

Well, we're jumping from NX4 to NX7.
On the manufacturing side, I was wondering if anyone
else has ran into this problem?

Toolpath intentions: Pick out a fillet on a non-planer cavity floor,using a 1/4" ball endmill.

In Fixed Contour setting up a open boundry with mulitple stepover's
(boundry is tangent to a cavity wall). On the engage, I set OPEN AREA at
.100 plunge, and set Against Part/Check at NONE.
(part geometry is body)
But graphics are showing the engage and retract starting/ending .100 above the cavity wall.
(If the cavity wall is 3" tall the engage/retract move is 3.100"
I want the tool to engage .100 above the cavity floor.



Any thoughts??

Heres a picture of toolpath --notice the closer it gets to the wall
the longer the engage (red) and retract (yellow) gets.

Yes, this post may qualify as thread necromancy

Another setting that may affect the engages/retracts is cutting-clearances-part safe clearance.

I cannot tell from the image if the floor is flat or not. If it is flat, another operation that may work well for you is z-level profile and set the cut level to optimized. I use it a lot with great results.
