I hope to measure our RV-M1 robot's accuracy utilising a CMM and calibrate it accordingly using ISO 9283 definitions.

Would anyone know the best method of doing this?

Thanks,

Peter

Enter as much information about your CNC hardware and software as you can - it makes it easier for everyone to know what you're talking about then.
Nobody here has ever done anything like it.
I imagine its a long, labourious procedure as every combination of every joint position will have different rigidity.
eg, With all joints pointing upwards, turning just the wrist will show pretty good accuracy / repeatability as the load is direct through all the joints
With the wrist pointing out sideways it'll be a completely different matter as the load forces act on the the motor/belts/chains as well.
Good luck :dumbfounded:
