hi there.
I'm breaking my head for two hours now on how to calculate de coordinates of te radiusses of the ring shown in the drawing aspecially the cutting point of the 114mm and 6 mm radius.
Not that i really need them i'm just doing a bit of braintraining and it pisses me off that i cannot figure out how to calculate them .
anyone got an idea on how to figure it out with just a simple calculator.
