You write from a material thickness of 16mm.
The width of the part (wall thickness) is perhaps the half.
So the depth increment of 6mm is almost as big as the width of the part (in XY). You have a spiral cutting edge. The material swings up unevenly, therefore the resonance marks come at your part. I would go here with low depth increment and very high feed. To do this I would glue the part to the ground to reduce resonances. Perhaps a milling cutter with a straight cutting edge will be better. i use different diameters with straight carbide indexable inserts for such works. This means that the cutting edge lies against the entire surface at the same time and generates less resonance.

If I write from mm/min the tooth load (0.04) is of course also in millimeters.
