    I use the Dynamic Mill toolpath in Mastercam the most.
    So I guess my answer to your question would be Adaptive?

    "Parallel Spiral with Clean Corners" in Mastercam, if for no other reason than it makes a cool-looking pattern on the floor.

    Regards.

    Talking Mastercam here (and this process for ally electronic enclosures):-

    1. Optirough. Select solid, let it run and 90% of the material is gone.
    2. Optirough rest mill (smaller tool) - running from the above stock model and it will take out the rest.
    3. 2D profile - set Z leaving .01mm on base face, and finish profile (shape depending but mostly ramping Z down for continuous cutting) and it finishes the Z level with the one finish path
    4. 2D pocket - finish base standing off the sidewalls (radial say 0.1mm) - straight path as it is usually the fastest for prismatic shapes

    Doing this you theoretically get a 0.01mm step at the bottom of the inside, but it isn't noticeable. And this process works everytime to give good finishes when you're using 6mm cutters that are 50mm stickout etc - still get good finishes with no squeals or diggins through overloading cutters etc.

    Using Siemens NX...

    1) Adaptive Roughing for large parts which have no delicate features.
    2) Follow Part for small parts and parts with delicate features. Similar to your Advanced, I believe, but has many corner and performance options.
    3) Rest Roughing always, also has corner and performance options.

    I rarely use any of the other types because IMO they generally are obsoleted by Adaptive and Advanced. Also IMO, Rest Roughing is simply another step and is not a "type".
