Abstract
A method of compensating the measurement errors of a measuring machine deriving from the deformations of a machine bed of the machine caused by the load exerted by a mobile unit of the machine on said machine bed, said method being characterized by comprising a first acquisition step in which first data regarding the constraint conditions of a workpiece on the machine bed are acquired, a second acquisition step in which second data regarding the deformation of the machine bed as the position of the mobile unit of the machine varies are acquired, and a third calculation step in which correction values depending upon said first and second data are calculated.
