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.

Method of determining the measuring uncertainty of a coordinate measuring device

A supporting element having a base positionable on a table of a measuring machine; a rod in turn having a vertical axis, and which is fitted to the base and movable axially to adjust the height of the supporting element; and an end portion fitted to the rod and cooperating with a position reference fixture moved by the machine; the supporting element also having locking means interposed between the rod and the end portion, and which are releasable to permit a limited amount of movement of the end portion with respect to the rod when configuring the supporting element.

A fixture for positioning and supporting parts for measurement on a measuring machine, the fixture including a number of reconfigurable supporting elements, each having a base positionable automatically on a reference surface of the measuring machine by a head of the machine itself, and a column, which is adjustable in height by means of a reference tool, and is subsequently fitted to a respective base.

Reconfigurable supporting fixture, particularly for a measuring machine,

An assembly for supporting and guiding a movable member of a machine along an axis 'X' relative to a support member of the machine. The assembly includes first and second slide surfaces on the support member lying in planes which intersect with each other and extend parallel to the 'X' axis, a pair of pneumatic bearing pads are fixed to the movable member and are slidable on respective slide surfaces. A third slide surface is formed on the support member and extends parallel to the 'X' axis in a plane inclined to the planes including the first and second slide surfaces. A third bearing pad is fixed to the movable member and is slidable on the third surface in an arrangement to balance the loads exerted by the first and second bearing pads.
