BradleyAttorney, Agent or FirmInternational ClassG01B 005/20Foreign Application Priority Data1999-02-22 RUAbstractA device and method for measuring deviations in shape of a generally cylindrical workpiece is disclosed. The device enables measurement of a number of shape-defining parameters while the workpiece is positioned in a machine tool, so that the workpiece does not have to be removed from the machine tool in order for the measurements to be taken. A steadying rest, for use on machine tools to hold a workpiece, especially one having a longitudinal central axis that is rotationally unsymmetrical or unstable with respect to the machining tool, in position to enable measurement of the shape defining parameters and shape deviations while the workpiece is mounted on the machine tool, is also disclosed.Field of SearchContinuous gaugingWith support for gauged article Concentricity Profile Member contacts successive points on the article With recording of contact member position at each point on the article LATHE Work rest HOLDER MOUNTED FOR MOVEMENT For yoke type RELATIVELY MOVABLE JAWS Rocking-element type Including pivoted yoke frame jaw carrier MACHINE Disk tool Rotary tool Rotary disk Work rotating Rotary work holder Rotary | |
