CAM : Point to Point along contour
(OP)
NX 7.5:
Does anyone have a good solution for generating a point-to-point drilling program that will track along a contoured surface?
This part has ~100 holes that need to be drilled normal to the machine table but the surface is heavily contoured. I could specify an R plane that is above the highest point of the part but then the drill will be feeding down for several inches in the deep part of the contour and it will take forever.
My first thought is to break it up into 4 or 5 zones, define a different R plane for each zone and just accept that there will be some wasted motion. We're only making a couple of parts. Anyone have an easier way?

NX will do 5 axis positioning to seperate holes within the same operation. Mke sure Use Arc Axis is active when setting the tool axis to Normal to Part Surface
If you don't have holes how are you defining the location?

I was planning to extract isoparametric curves from the hole edges to get center points that I can position to.
RE: CAM : Point to Point along contour
OK now it think I understand.
When creating a drill operation select all the holes as the geometry. The tool should start at the top of each hole. It should be as simple as that. There should be no need to create extra curves. Do not use any part surface and if they are modeled to the correct depth then you can use "Model Depth"

Thanks for the time John. I'll try to come up with something more challenging next time.
