For now my target is to work with FreeCAD/Path. FreeCAD uses a geometry
engine based on Open CASCADE. I'm looking at some physics engines now to
handle the collision avoidance between the tools, material and work holders.
I'm am also looking at being able to input factors for the tools and
material to be able to create more optimal paths than just raster scans.

arm and tool steel vs 60xx aluminum.

Hi Bari,
Though I'm no expert, your goal is admirable. I would say typically I do
tend to use the larger tools first when feasible (i.e. excluding situations
where I might have to drill first). I try to use an adaptive tool path
whenever possible too. I then move to one of many finishing strategies
(contour, horizontal, pencil, etc.)
I think traditional roughing was probably rather raster oriented. Probably
just work in a constant stepover and depth of cut and go round the part in
a roughly square path. However, I don't know because I have very limited
experience with CAM packages prior to Fusion360 about 6 years ago when
adaptive was pretty much standard. I dabbled with MasterCAM in about 2005,
but I can't recall if there was an adaptive tool path back then. I don't
believe there was, but I never dug that deep.

What are your approaches to machining when using 4+ axis machines?
Hog out as much as possible first using the largest roughing tools first
then moving to smaller?
Any fine points to consider?
One vendor of 5-axis CAM markets adaptive technology to speed up the
process. Not exactly sure what they used to do when creating paths with
their older software vs newer.
