Coordinate Measuring Machines (CMMs) have been widely used in industry in
order to determine the form / dimensional tolerances of workpieces with very
complicated geometrical shapes. Therefore, CMM is an important tool during the
manufacturing and quality control phases. Workpiece to be measured on a CMM is
probed via touch trigger probe through its stylus tip. In other words, by virtue of the
touch trigger probes CMM can acquire the dimensional data of the workpiece that is
to be measured. Therefore the probe has become the most vital and fundamental
part of the CMM. In this thesis, a novel type of touch trigger probe / scanning probe
is proposed. The proposed probe can also be used as a scanning probe for different
applications. The main purpose of this thesis is to develop a novel type of touch
trigger / scanning probe that has different kinematic stage and sensing stage than the
other probes currently used in the industry. Giant Magnetoresistive (GMR) sensors
are used for building the sensing stage of the proposed probe. GMR sensors are
selected due to their outstanding sensitivity to small disturbances. Furthermore, in order to test the proposed probe / an anvil gauge setup is designed and proposed in
this study. Finally, proposed probe is tested on a three-axis computer controlled
electrical discharge machine (EDM), and the results acquired from those
experiments are discussed.
