Abstract: 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 includes (i) using the machine tool to move the probe holder relative to the carrier along a pre-programmed scan path, (ii) measuring acceleration whilst the pre-programmed scan path is traversed, (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.
