With adaptive clearing toolpaths, you can choose to have a very deep depth per pass, and very low radial stepover such that the tool engagement is similar to having a low depth of cut but large stepover (the DOC/WOC balance strategy). On a Shapeoko, high DOC and low WOC is not often the optimal solution though, so if you are concerned about cutting times / material removal rate in addition to minimizing the tool breakage risks, you probably need to study the various combinations to optimize things, i.e. cutting parameters that will both limit tool deflection to a given limit while maximizing MRR.
@gmack came up with a cool spreadsheet that computes MRR and deflection (among many other things)
I can’t quite picture your project and toolpaths. If you can upload your f3d file, we can probably collectively have a look at it and see if we can propose optimizations, or at least brainstorm together around it ?
