The corners are just a simple curve and the profile operation is similarly simple. Since I don't want the cutter to travel all the way around the plaque but rather just cut the corners, I have to move those arcs and line segments into a new sketch. Then I select the sketch and add a profile operations. I'm cutting in red oak which is quite hard so I want the cutter to step down just a little bit at a time and make many passes.
With profiling operations, one thing to consider, is what will happen at the end of the cut when the stock and the part are no longer connected. The profile operation has a feature for 'tags' which are just material left uncut that can be removed by hand. Without them, the part might move into or away from the cutter and be damaged. In this case, the stock is well secured and the pieces cut off shouldn't cause a problem.
