<p>A coordinate positioning machine (20) is equipped with either an optical probe or a contact measuring probe (40). Movement of the head (22) of the machine to enable the probe (40) to scan an unknown surface is controlled by predicting the position of a subsequent point to which the head of the machine is to be driven upon the basis of three most recently measured points P1, P2, P3. The prediction of the subsequent point P4 is performed by machine control (30) in real time.</p> |
