hey guys! I'm having trouble validating a measurement method. I am finding different values of concentricity between two diameters. We have already tested leveling in different work planes and positions and the values do not match when compared. in DCC mode I am always creating a plane and a cylinder, where I level and give origin to the cylinder and the plane is my height reference. In this cylinder that I level, I measure three diameters and after measuring them, I measure another larger diameter that is about 20mm away from them and I make the concentricity between them.depending on whether I place the piece lying down or standing up, changing my work plane, my concentricity varies from 0.070mm to 0.200mm. what do you think it could be?
In addition, in the ISO world, the dimensioned circle and the datum must be coplanar for concentricity (see ISO 1101). One of the problems for designers and metrologists is that concentricity and coaxiality have the same graphical representation.
Yes, but the ASME standard got rid of concentricity. There is a tendency for the standards to take over certain developments from each other (not all, of course), and from what I've heard, it can be expected that ISO will follow the elimination of concentricity.
