hello.
We have 2 Kuka KR240 r2900 ultra's purchased 18 months apart from Kuka and integrated as CNC with spindle's by the same third party integrator.
we use PowerMill as out programming software. using pretty much the same Post processor to output our SRC files.
programming them separately, one will follow programmed toolpaths 100% as programmed and the other will very often approximate a sharp corner with a large radius either leaving material in the job for an internal corner or cutting through the part for an external corner. both robot config files have been checked and both poste files have been checked to no outcome.
it has both myself and integrator puzzled as he has never come across this issue before in over 100+ robots he has integrated for the same process. no matter what smoothing settings we use in PowerMill the robot does what it wants to. if you run the same program on the older robot it follows the programmed corners as programmed without approximating.
is there a setting somewhere within the new robot we are both missing??? has KUKA changed something?
