Method for validating a workpiece measurement in a dimensional metrology hand tool |
摘要 |
A method for validating a workpiece measurement in a hand-held spatial dimension measurement metrology tool comprises vibrating a portion of the metrology hand tool using the vibration excitation element; sensing a vibration signature using the vibration sensor configuration; identifying a valid contact state between the metrology hand tool and the workpiece based on a vibration signature criterion; identifying a valid seating state based on a measurement stability criterion applied to a set of dimensional measurements of the metrology hand tool; and indicating that a dimensional measurement is valid for a dimensional measurement that is obtained when the valid contact state and the valid seating state occur simultaneously. |

1. A method for validating a workpiece measurement in a dimensional metrology hand tool, the
dimensional metrology hand tool comprising a first workpiece contact surface included on a first member and a second workpiece contact surface included on a second member that moves relative to the first member, a dimensional measurement sensor for measuring a separation between the first and second contact surfaces, and a signal processor, the method comprising: vibrating a portion of the metrology hand tool using a vibration excitation element of the metrology hand tool; sensing a vibration signature using a vibration sensor configuration of the metrology hand tool; identifying a valid contact state between the metrology hand tool and the workpiece based on a vibration signature criterion applied to the vibration signature; identifying a valid seating state of the workpiece as seated against the first and second contact surfaces based on a measurement stability criterion applied to a set of dimensional measurements of the metrology hand tool; and indicating that a dimensional measurement is valid for a dimensional measurement that is obtained when the valid contact state and the valid seating state occur simultaneously. |
