Abstract
A coordinate measuring machine (CMM) carries a probe and is controlled by a controller to drive the probe to take measurements on a workpiece. In order to reduce the effects of acceleration-induced deflections of the probe on the measurements made by the machine, accelerometers are provided to measure the accelerations of the probe and to produce signals indicative thereof. The acceleration signals ( ) are passed to the controller (FIG. ) where they are integrated ( ) and filtered ( ) before being passed as velocity signals ( ) to a summing junction ( ) from which they are fed to a velocity feedback control loop ( ) which reduces any changes in the velocity (and hence deflection) of the probe due to the accelerations.
