Our Makino S56 can mill around a radius (or circle mill) without leaving quadrant marks, however our Doosans leave essentially 4 marks when circle milling an ID. If we Finish mill around the outside of a part and it has an arc (at the top of that arc there will be a line almost like it comes off the piece for a split second) Is this a parameter we can adjust , I have seen a few things on static friction compensation parameter but am not 100% positive if this is parameter issue vs machine just not being as good as the makino lol.
 
Have not checked it, but our kitamura mycenter does it as well and it is brand new? Backlash compensation acceleration is something I havr been reading about as well.. hopefully someone has the answer. Do you guys get these quadrant marks on any of your machining?
