Try with MergeAllFaces.

Hi Benedikt, welcome to the forum!

The problem is that operations ChamferEdge, FilletEdge and BlendEdge only work on the surfaces that are attached to the edge. In your case, where the curved edge meets the circular edge, three surfaces come together that should be affected, but each edge is only attached to two surfaces, so the third surface does not get chamfered. This is a known limitation that we’re hoping to do something about in the future.

The solution for your case is what was suggested, use MergeAllCoplanarFaces and then the chamfer can be done.
