Abstract: An articulated sensor head includes three different sensor modules. A first of the sensor modules is carried on an extended shank that is mounted in a pivotable fashion from an articulating wrist. A housing carrying a second and a third of the sensor modules is releasably fastened to the extended shank. The second and third sensor modules are carried by the housing in a fixed angular orientation with respect to an orientation of the first sensor module.

Abstract: Measurement routines are established for automating multi-sensor measuring machines. Selections of feature types, sensor types, and closest points on computer models information is processed for distinguishing whether the features intended for measurement lie on a boundary or on a surface of the part to be measured. Interactions through a graphical user interface to a code-generating computer allow for the selections to be made and corresponding measurement instructions to be generated.

Abstract: A graphical representation of a feature and associated tolerance includes a memory storing a description of the feature including at least one nominal dimension of the feature and an associated tolerance; a graphical representation of a nominal definition of the feature; and a graphical representation of the tolerance zones, derived from the nominal definition of the feature.

Abstract: A precision measuring machine, such as a coordinate measuring machine, includes a probe assembly fixed to a movable member of the machine. The probe assembly includes a probe tip. A calibration object is detachably secured to the movable member in fixed relation to the probe assembly. The probe assembly articulates into a position such that the calibration object may be probed by the probe tip to recalibrate the probe assembly.

Abstract: A computer interface device for a coordinate measuring machine comprises a trackball that transmits perpendicular movement signals to a computer in response to corresponding perpendicular tangential movement of the trackball. The computer is interconnected with the coordinate measuring machine and normally receives measurement data corresponding to a location of a probe on the computer. The trackball is located adjacent the probe so that a user grasping the probe can manipulate the trackball to transmit data manipulation signals to the computer. Typically, the trackball moves a cursor about the computer screen. A plurality of data entry buttons are included on the interface device and enable the user to execute computer procedures selected by the cursor.
