Lathe Grooving with same width cutter as groove

In a nutshell, how do you guys program say a .078" groove with a .078" wide cutter? I have lied to the stock to leave in Z by a .0001, which technically works, but it also gives me an annoying tool collision error.  Any ideas?  It also gives me two passes, but since I have an edge break on both sides, I guess that's ok.

I don,t use groove toolpath for this, I use finish profile and pick either one of the walls.

The trick here is tool clearance in plunge parameters. You could do the same for the edge breaks

In other news... something else I do when creating a turn profile is put .005 or .01 fillets on EVERY intersection

that will be turned. Reason being whenever there is a change in tool direction a burr is created as, depending on tool rad,

the tool looses contact with the work piece. Putting a little rad on the intersection forces the tool to stay in contact

and no burrs are created.
