A number of new or revised services in dimensional metrology are presented. Included are: a lower cost, high accuracy calibration for sphere diameter; reduced uncertainty in roundness calibration; a new instrument for measurement of the thermal expansion coefficient of gauges and other material; extended capabilities of ring gauge calibration on the M48 CMM, and a system for in-situ calibration of deformation of gauge blocks in mechanical comparison.
