clear set of knowledge gaps are identified in these fields. Secondly, a novel concept of
three-dimensional measurements using a rotating wire as a probe tip and acoustic emission
for contact sensing is introduced. The operation and measurements of the rotating micro
probing based on acoustic emission (AE) sensing are validated experimentally. Initially,
the ability of the rotating microprobe tip based on AE sensing to counteract the measured
surfaces interaction rubbing is investigated. Other areas of validation are in the
determination of the probing point repeatability, the straightness, and probe tip calibration.
Thirdly, the acoustic emission signal and its characterizations of the probe tip touches are
studied. The behavior of the rotating probe tip focusses on the threshold, touching time and
as well as measured materials type that has an effect on probing accuracy.
Finally, the estimated effective diameter and approximation threshold are modeled.
This work is directly aimed at ensuring that the developed rotating probe tip based on AE
sensing is capable of operating in an industrial metrology environment.
It is concluded that the developed rotating probe tip based on AE sensing will be able
to address the current needs of the micro-CMM community. On the other hand, it is

possible that the rotating wire probe tip based on AE sensing can measure micro holes less than the achieved in this work, further increasing its usefulness.
