I have part that we are working now that looks like a 40 degree segment of a wheel. kind of like a banana shape. We are measuring the rads with a mitutoy Manual CMM with geopack and mcosmos. We cannot accurately measure the radius'. The CMM is giving us numbers that are .005-.010 big or small. And not repeating. The Radius' have +-.003 tolerance. I am not to familiar with the CMM and its software as it is new to us. What is the proper way to check these? The parts are good because they have been inspected by the customer on their CMM. Talking with someone there, they said there is a specific way to check arc segments? Any one care to chime in?
