ABSTRACT:
A distance sensor is arranged to be moveable relative to a workpiece, during a machining operation this movement having a limit at a position where a finished workpiece would be within an accurate measuring range of the sensor. As machining progresses the sensor is moved towards the workpiece, stopping either when the separation of sensor and workpiece reaches a pre-set value of when the sensor reaches the limit of its movement. If the separation of sensor and workpiece reaches the pre-set value the sensor is moved away from the workpiece and then towards it again, repeating the cycle. If the sensor reaches the limit of its movement it remains in this position and measures its separation from the workpiece for the remainder of the machining operation.
