Hi Danny, Thanks for the time there.
I'm not the best communicator.
I have a model with that original fillet on it (The cad/cam package fillets it that way also) and I was trying to understand How it came about that way (From Michael) and looking at how to cut it (You).
I think I solved it but wont know for a bit as our machine is tied up doing some jobs at the moment.
The issue is the original .125 circle used to cut out the hole gets stretched due to the "projection" of the curve on the surface of the cylinder. Most have already suggested using a 3d toolpath to cut it and that works well and is a done deal, though me, being the nut that I am, am trying to figure out how to do it with a profile job (Much faster than a 3d toolpath).
My solution is to take the original 1.25 circle and convert it with "axis-dim*(360/(Pi*2))/radius", which is essentially doing the wrap, then I can run a profile operation on it with a 4th axis rotation. I think this will produce the "Subtended Angle" that we want but I cant proceed until I can run some toolpath and see if the theory jives up.
Thanks again,
Burr
