SENSOR AND METHOD FOR LOCATING A DISCONTINUITY

摘要

A method and apparatus for locating a discontinuity such as a hole in a work piece is provided. The apparatus includes a probe having a shaft attached to a handle for locating a discontinuity in relation to a coordinate system. The probe includes an end unit attached to an end of the shaft opposite an end of the shaft to which the handle is attached. The end unit is configured to contact a surface associated with the discontinuity and move in relation to the coordinate system to align the end unit to an axis associated with the discontinuity. At least one position sensor is located entirely within the shaft and configured to sense the position of the end unit in relation to the coordinate system. The shaft includes a plurality of bores and the sensor is located within at least one of the bores.
