MEASUREMENT METHOD

A method of determining a form measurement for a curved feature of an artefact. The method includes a positioning apparatus relatively moving the artefact and a measurement device relative along a curved path in a first direction, to obtain a first set of data points along the surface of the curved...

Summary:A method of determining a form measurement for a curved feature of an artefact. The method includes a positioning apparatus relatively moving the artefact and a measurement device relative along a curved path in a first direction, to obtain a first set of data points along the surface of the curved feature, and the positioning apparatus relatively moving the artefact and the measurement device other along a curved path in a second direction, opposite to the first direction, to obtain a second set of data points along the surface of the curved feature. The method further includes using the first and second sets of data points to determine a form measurement for the artefact.
