  • Patent number: 7905027
    Abstract: A method for determining probe tip diameters with improved accuracy and reliability that includes performing a routine for determining probe tip diameter multiple times with the arm of the coordinate measurement machine in different machine positions. Diameter values associated with each of the calibration routines may be combined in a manner that provides more accurate diameter measurements.
    Type: Grant

  • Patent number: 7752003
    Abstract: A coordinate measuring machine compensates for hysteresis error caused by friction at the non-driven end of the bridge. The bridge may have a single drive and/or a single scale. The methods, systems, and apparatuses compensate for errors in the x-direction and/or errors in the y-direction caused by rotation of the bridge. Some embodiments compensate for hysteresis errors in the x-direction caused by a vertically-movable ram.

  • Patent number: 7669344
    Abstract: A single-scale, single-drive coordinate measuring machine that compensates for hysteresis error caused by friction at the non-driven end of the bridge. The coordinate measuring machine is calibrated to estimate hysteresis effects at one or more distances from the scale. Measurements of workpieces are adjusted based on the calibration data and the distances of the carriage from the scale at the point of the measurements. The scale and the drive system may be positioned on opposite guideways.

  • Patent number: 5535524
    Abstract: A coordinate measuring machine has a single vertical column mounted to a horizontal table for moving in the x-direction, and a carriage mounted on the column for vertical movement in the z-direction. The column is moved with a motor that drives a rack and pinion. The carriage supports a y-rail that moves in the y-direction. A first damper is positioned over the z-rail in the -y direction so that the column is intermediate the damper and the probe. A second damper is positioned at an end of the y-rail near the probe. The dampers reduce both large amplitude transients, as well as steady-state vibrations that are caused by the motor cogging and gearing between the motor and the rack and pinion.
