If you think of a tiny you walking along on the top of the part, following the cutter as it moves about, left and right will be as you would see it. Assuming climb milling with a CW tool rotation as you look down on the workpiece, and you are machining the exterior of the part, you then want to progress clockwise around the part. Walking behind the cutter, the tool would be on the left of the part. So, you would use G41.
