Looks like a legit bug in MillFace. https://freecadweb.org/tracker/view.php?id=3324
I have a fix pending here:

I tried to use the simulation-feature but at least on my setup it results in a brown blob:

When I hit "play", I see the tool moving but the stock isn't updated. I kind of remember this feature working properly in the past, can't say for sure and on which platform (ubuntu/windows).
It's the tool geometry. Please read my remarks in the walk-through in the documentation.
Read the manual now it works ;)

Awesome that was lightning fast, thanks sliptonic!

If it's not too much to ask, could someone clarify, why the millface operation area is not derived from the stock? If you take this for example:

If you first face-mill your stock only the area directly above of the part would get milled down and in the next step (the contour) the tool would still crash in the left over stock material. Am I missing something because I thought that was what the "boundary shape" setting was for, but it doesn't change anything if I swap from "perimeter" to "boundbox".

The MillFace has an option to use either the Part Perimeter or the Part BoundBox. It should probably have a third option to use the Stock BoundBox.

Want to add a feature request for that to the tracker?

I requested the feature:

I hope I got that kind of right :)

Cheers!
