VERFAHREN ZUR MESSUNG EINES WERKSTÜCKS UNTER VERWENDUNG EINER BEARBEITUNGSMASCHINE

摘要

A method is described for measuring a workpiece on a machine tool using an analogue probe having a deflectable stylus. The method comprises the step of taking a workpiece having a nominal surface profile, the workpiece being located within the working area of the machine tool. The machine tool is used to move the analogue probe along a predetermined (known) measurement path relative to the workpiece whilst deflection of the stylus is measured. The analogue probe is moved relative to the workpiece at a speed greater than five millimeters per second and the predetermined measurement path is selected to provide intermittent contact between the stylus and the workpiece.
