Dynamic toolpath question

Recommended Posts

I'm sure there is a way to do this and the quickest way to find out is to just ask I guess.

Imagine you have a 10" diameter pipe with a 2" wall thickness with the bore in line with the Z-axis on a mill.  I need to use a dynamic toolpath to rough several features in the wall, on the inside of the bore only.  I can create a boundary easily enough and create a toolpath to stay inside this boundary.  The problem with this is I end up cutting a ton of air as it will treat it as a solid bar...  How can this be cleaned up so it will rough the features without cutting air?  I know I can create an additional chain to minimize how much the tool machines air in the bore but then it wants to treat this region as a pocket and helix down.  Ideally I would machine this with a 'from outside' approach.  Any ideas?

DOH!  I just saw the 'air regions' tab...  Ugh, never mind...
