Cutting with 1/4 the going back in with a 1/8

Hi @Newguy,

Welcome to the community !
We had a very similar thread recently, with a good tip from @fenrus:

Flag Star Work Flow

I want to make an American flag and rather than cut the stars with a V bit I’d like to use an end mill. However, I’d like the points of the stars to be nice and crisp. My thoughts are to make an initial inside left cut using a 1/16 end mill and finishing what remains inside with a 1/4 end mill. However, when I run a simulation there are some small pieces that don’t get cut out that should be. That means making a third run at it to eliminate them. Considering there are 52 stars I am beginning to …

In short: there is no built-in capability for “rest machining” in CC (=what you are describing), but there is a good way to emulate it by just doing an inside contour with the smaller endmill after the initial pocketing with the larger endmill, “as long as each next bit is at least half the diameter of the previous”
