What is the width of an outline cut? Can it be made larger?

I want to cut out a box section from a solid piece of carbon PEEK. I’ve been advised that I will have problems if I try to make the profile cuts the same width as the end mill I’m using. When programming tool paths, does Easel avoid this issue by making the cuts slightly wider than the bit, or does it just do one straight line per pass to produce a final cut the same width as the bit?

Either way, is there some place this information is available to the user, and can the cut width be adjusted?

AFAIK, the only way to control this is to add additional geometry and make the cut as a pocket.
