Pipe hole

Hi,

I've been playing around with SW CAM (the standard add-in for SW Prof). I'm trying to make a hole in a pipe where it cuts around 5 mm into the material in first cut and then finish the rest of the material in the second and final cut (around 2 mm). It only have to cut the contour of the hole. I got it working on a flat plate, but this seems a little more challenging. 

I need a little help to how I get around this problem with the 3d curvature hole, and is it even possible in the "standard" version of SW CAM?

I hope someone got a clue on how to do this, I have inserted an example on how the pipe could look like with a diameter on around 100 mm.
