GH pipe branching Cleanup for CNC?

1. The pipe component with caps on, created this original tree type branching geometry.
2. I then Boolean inter sectioned to cut the pipes horizontally, manually in Rhino.
3. I also manually Boolean treated some of the pipe intersections in Rhino
4. I want to create a path for a bulb nose CNC bit to cut all the branch paths to the depth of the half pipe.

Question:1
Does the half pipe path for CNC cutting need to be entirely Boolean free and uninterrupted?
Note: 10 lane pipe intersection at the center of the pic has not been dealt with yet.

Question:2 Are there other GH components that are capable in helping with this type of Boolean pipe cleanup?

TIA!

Thanks Siemen: However my Question: 2 still has issues. Its either do what Martyn suggests " boolean union all the pipes and then subtract the result from a block " or does GH also have the tools to do that with components?

GH should have the tools to do that with components, I mean you can boolean union and subtract in grasshopper. But my experience with trying to boolean union lots of parts in grasshopper (but also in Rhino) so far is that it either fails or tends to become very slow.

Not sure if I'm answering your question correct.

Siemen: You answered by question, I have the same doubt about doing many Booleans one after the other.

Thinking out loud about this, (I'm no expert in these matters). it appears perhaps an orderly list maybe required for all these booleans to be done one after the other. Also a Timer would be a great asset that tracks the anticipated time to complete the task, hence the user would know roughly, if he or she time to order and eat a Pizza, instead of simply starring at a blank white screen, on my computer, waiting for something to happen. :)
