Yea, it can do that as long as the wood will fit. Depending on size you might have to cut the pieces by themselves. You can’t get perfectly square holes, but you can compensate for that in estlcam. Set up all your cuts, then highlight your parts and click on “Automatic functions” in the top menu. Then select “Add corner overcuts”. This will circle all your inside corners so you can verify it got them all. I use the defaults and so far on the couple things I’ve needed it for that works. What it does is at all the inside corners it bumps the endmill out to cut a small divot so the mating part will have clearance. In the attached pic the overcut is on the left, normal path is on the right.
