Using TP20, 3 way (T-shaped) build. Taking about 50 vector points around a cylinder and constructing a cylinder (least squared). Output cylindricity and it measured 0.0024" yesterday afternoon. Calibrated the probe this morning, re ran the same part and cylindercity measured 0.0011". All the other diameters and distances measured were different by 0.0001"-0.0002".
acgarcia your machine and head probe can guarantee that repeatibility?
I don't know your industry, but in a 3 way build on TP20, measuring whit 50 points, it's completely normal and acceptable get 0.0013 difference between measurements.
