Abstract:
1. A method for calibrating apparatus comprising a measurement probe mounted on a machine, the machine being arranged to capture machine position data indicative of the position of the measurement probe relative to an artefact, the measurement probe being arranged to capture probe data indicative of the position of a surface relative to the measurement probe, the method comprising the steps of; (i) moving the measurement probe at a known speed relative to the artefact whilst capturing probe data and machine position data, the measurement probe being moved along a path that enables probe data to be captured that is indicative of the position of two or more points on the surface of the artefact relative to the measurement probe; and (ii) analysing the machine position data and the probe data captured during step (i) and determining therefrom the relative delay in capturing probe data and machine position data.
