摘要： A calibration device (30) for a machine tool is described that includes a base (36) attachable to a machine tool and a calibration artefact (32), such as a sphere of known radius. A deflection mechanism attaches the calibration artefact to the base and allows movement of the calibration artefact (32) relative to the base (36) when an external force is applied to the calibration artefact (32). The deflection mechanism also maintains the calibration artefact (32) in a defined rest position relative to the base (36) in the absence of an applied external force. A sensor (46) is provided for sensing the extent of movement of the calibration artefact (32) relative to the base (36). A method of using the device (30) with a reference tool to accurately determine a position of a calibration artefact (32) is also described.

摘要： Apparatus and method for fitting a workpiece to geometric design data of a workpiece. Nominal data points are selected from the geometric design data. Command codes are created to generate measured data points. The measurement data points have associated nominal measurement points which are used to fit the workpiece to the geometric design data. The apparatus and method may also be used to determine whether a workpiece is within tolerance and for process control.
