Abstract: An assembly for connecting a measuring head to a measuring robot, the assembly having a flange integral with a supporting member of the measuring robot; isostatic supporting elements interposed between the measuring head and the flange; and a rotary ring nut carried by the flange and movable between an angular position permitting insertion of the head, and an angular position locking the head; the ring nut having elastic elements generating a preload on the isostatic supporting elements; and the isostatic supporting elements defining respective switches of an electric circuit forming part of a safety system for detecting shock on the head.

Abstract: To determine the measuring uncertainty of a coordinate measuring machine, a real measurement is first made of a workpiece, with any compensation provided for on the machine disabled, to obtain a measured value of one or more required quantities; a predetermined number of simulation cycles are then performed according to the Monte Carlo method to statistically vary a given number of influence parameters affecting the measurement and generate simulated values of the required quantity; and the measuring uncertainty value is determined by statistically analyzing the deviations between the simulated values and the measured value.

Abstract: A fixture for positioning and supporting parts for measurement on a measuring machine, the fixture presenting a number of reconfigurable supporting elements, each presenting a first portion positionable on a reference surface of the measuring machine, a second portion positionable in relation to the first portion in a direction perpendicular to the reference surface, and clamping members for clamping the first portion in relation to the reference surface and the second portion in relation to the first portion; and a gripping tool movable automatically by the measuring machine and cooperating with the second portion of a supporting element in a position of mutual engagement to set the supporting element in a predetermined position; the gripping tool presenting control means, which, in the aforementioned position of mutual engagement, provide for simultaneously releasing the clamping members clamping the first portion and second portion of the supporting element to enable the supporting element to be reposition
