I'm trying to use an hole making operation in a pre-drilled hole, but the feature geometry doesn't take into account the pre-drilled hole. I'm expecting no material in the core of the hole. (see pics). I defined the part material and the blank material.
I also attached a test part
Thanks in advance

Solved! Go to Solution.
I just put operation into the feature in geometry view in order and generate.
You had it in "unsused items"
The operations are okay. I put the other operations in unused items, because 1 operation in enough to make the problem clear. The operation sees that there's material in the core of the hole, but that's already been machined in another setup. That's why I have to change the start diameter into 40mm to get a good toolpaths. I don't want to change this start diameter, because I'd like to use this feature in a FBM like way. With other words, I don't want to do any manual interference to get good toolpaths....
The use case is understood. This is not possible in NX CAM because it doesn't "know" about previous setups. We are working on a Multiple Setup solution that offers this kind of capabilities but it's still under development.
The only option today is to manually define the start diameter in the "second" setup.

Thanks for your reply. It's clear to me now.
In fact this "pre-drilled" hole is a casted hole in a casted workpiece (see pics). So in this case there will be no previous setup. I tell this because, if you're only develop a solution for "second" or multiple setups this will not help us in this case.. Maybe something to take into account.
You can also just specify the blank as an offset added to the design part, which works in most cases.
