Whether or not you get a wavy line/arc depends on the direction of cut (climb/conventional), the cutting force and the friction of the slides. Either way you will get a 'blip' on the corners, or wherever any axis changes direction. Here's an example:




The corners should be smooth, but as you can see each corner has a line/offset portion where the axis changed direction. For that part it doesn't really matter - it's still shiny

That was on my milling machine which currently has more than it's fair share of backlash.

This part was made on my router which has very little backlash, so the corners are smooth with no 'blips':
