| Method for measuring an object using a scanning probe carried by a machine tool having a probe holder for the scanning probe and a carrier for the object, the method comprising the steps of (i)using the machine tool to move the probe holder relative to the carrier along a pre-programmed scan path (100), the pre-programmed scan path comprising at least one first region where the movement along the pre-programed scan path is at a first feedrate, at least one second region (106a, 106b, 106c, 106d) where the movement along the pre-programed scan path is at a second feedrate, and at least one acceleration zone (108a, 108b, 108c, 108d, 108e, 108f, 108g, 180h, 109a, 109b) located between the at least one first region and the at least one second region, (ii)measuring acceleration whilst the pre-programmed scan path is traversed (202), (iii)collecting probe data whilst the pre-programmed scan path is traversed, and (iv)using the acceleration measured to identify at least one acceleration zone of the pre-programmed scan path and thereby determine one or more positions along the scan path at which the probe data of step (iii)were collected. |
