Did u try to lower the feedrate?? Try 1000 or 500 instead of 2000... Maybe the motor strenght isnt enough to move the mass of axis so quickly or maybe the gain (kV) of axis is too big or too small for one of the axis so it gets overshot of position that result in quality degradation.

I've seen something similar before. In this case, it was not the machine, rather it was the CAM software. It was generating discrete layers on every surface, which was good for the most part. But the closer a surface came to being parallel to any axis, this pattern would become very obvious.
Have you tried re-creating the cutter path with different strategies enabled?

While it seems you have gotten several things to try for you problem in this SHOP PHOTOS section, I think you would be better served by posting this question in the FANUC section.
There are many more FANUC users out there that might have a solution.
Good Luck
SMCTL claim to be the largest MTB in the world with 60yrs experience, in this case I would think the ball is in their court to come up with a viable answer, you shouldn't have to come to a CNC forum IMO?

does the spindle run smoothly or is there noise/whining/whirring?
can you do normal flat surface milling and obtain smooth surfaces?
maybe spindle bearings? I have seen similar things in the past and the spindle bearings were the cause.
Are you using the highspeed machining option for the machine?
G5.1 Q1 / G5.1 Q0?
It gives the controller a look ahead
