  • Patent number: 9879967
    Abstract: A method for compensating measurement errors caused by the deformation of a component defining a slide axis in a measurement machine, comprising the steps of calculating the curvature of the component as a function of the difference between the current temperature Tc and a reference temperature Tr at which the geometric compensation map of the machine has been obtained, calculating correction values for the compensation parameters stored in the compensation map as a function of the curvature, and updating the compensation map with these correction values.

  • Patent number: 9212888
    Abstract: A method of compensating the measurement errors of a measuring machine (1) deriving from the deformations of a machine bed (2) of the machine (1) caused by a load exerted by a workpiece to be measured on the machine bed (2), characterized by a first acquisition step (15) in which data regarding the weight of the workpiece and the conditions of constraint of the workpiece on the machine bed are acquired by a measurement and control unit (12) of the measuring machine (1) and a second calculation step (16, 17, 18, 19) in which correction values depending upon said data are calculated by said measurement and control unit (12), wherein the first step (15) includes selecting a standard load condition representing the load of the workpiece from among a plurality of standard load conditions; and the second step includes the step of calculating values correlated to the deformation of the machine bed (2) under the load of the workpiece represented by the selected standard load condition as a linear combination of corre

  • Patent number: 8868367
    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.
