Which Operation should I use when I want to mill sharp edges?

In Profile Contouring, I should calculate offset from Bottom and from Contour.

In example, I want to cut sharp edges by 0.4mm and create offset from Contour 2.6mm and from Bottom -3mm.

If it is 90 degree mill tool on top, then it is simple. But if I use mill tool with another angle, I have to use Formula. Maybe we have some easy method to mill sharp edges. In some CAM there is specific operation, which do this job.
