Abstract:
In combination with a Coordinate Measurement Machine (CMM) useful for the measurement of structure geometry, an improved piezoelectric touch probe comprising:a control unit securable to a robotic arm of said CMM having a driver to create an acceleration/vibration driver signal; a vibration sensor, having an operating frequency band, electrically coupled to said control unit; and a flexible and removable stylus coupled to said vibration sensor; whereby said driver signal causes vibration of said flexible stylus wherein said vibration sensor measures a resonant frequency created by said stylus in relation to structure geometry; wherein said vibration sensor further includes means to amplify a vibration signal received from said stylus; and, wherein said means to amplify the vibration signal is a suspension of said flexible stylus that is coupled to the dynamically tuned structure.
