High Accuracy and Repeatability for Multiple Parts

Taylor Hobson is aware of the significance of ensuring high reliable, repeatable and accurate measurement data. To this end, the company carries out extensive analyzes on its products – an example of which is presented here. Multiple traces have been taken and the results display the average error profile (dark blue line) in addition to the envelope for part variation (light blue).
