Chamfer endmill simulating incorrectly

[hatch789]

Hi guys, I have a really simplified version of a much more complex part I'm making here as an example for you. This real part has a lot of carefully chamfered holes that I'm trying to ensure things are going exactly as they should before I cut material.

Why on earth is this chamfer mill acting so odd in simulation? It's showing collision and it's simulating a bunch of extra material being milled out than it should. The part cuts perfectly on the machine but often I use simulation to dial a process in and then run it on the machine. Here however the simulation is way off for me.
