Probe Calibration and Form Resutls

Can probe calibration affect form results?

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".

  • If you are using a 3 way probe and taking hits with each probe then probe calibration could have an effect on the measurement 100%. It is unlikely to have a .0013" impact on the results unless the probe (probes) have changed since the last calibration. I don't think it is the reason.....but it does have the potential to change the readings.
