how to force a start position

[headshread]

hi all
i have a triangular pocket that needs milling out.in fact i have 300 triangular pockets to mill out
i have created a point in the middle of this triangle so that i can u drill to depth.i now need to get a milling cutter into this hole and mill this pocket out.
how can i force the milling cutter in the hole.
i am using nx6 ,boundary milling,contour profile.at the moment the tool goes in off centre and follows the profile ,stepping out 1.25mm on each pass until it reaches the walls.this may sound a easy problem to solve but i am scratching my head a bit.
the job is more complicated than it sounds as the triangular pocket is on the side of a truncated cone and the base of the pocket is curved

Have you tried to use Engage from a Point?

I have in the non cutting moves ,you can engage from a point. I highlight the point then rerun ,but the tool path doesn't change.

In the Transfer tab you have start region or start drilled point - select the "Drilled point" (at home not sure what it's called...) Then for your engage under Closed Boundary use Plunge with a distance you'd like the tool to feed down before hitting the floor. Works great.
