The method includes the steps of generating a succession of laser beams in different directions by means of an interferometer, and, for each direction, moving the target into a number of points along the beam; measuring, by means of the interferometer, the abscissa of each of the points from an origin located along the direction of the beam; acquiring the coordinates of each of the points by means of the machine; and determining error parameters of the machine on the basis of the abscissas measured by the interferometer, and the coordinates of the points acquired by the machine.

Abstract

A method for determining dynamic errors in a measuring machine that gives the position (xa, ya, za) of a mobile element of the machine (3) in a working space with respect to a reference system (X, Y, Z), comprising: a calibration step (100), defined in which is at least one input-output model (M1, M2, Mcompl), which describes the dynamic behaviour of at least part of the measuring machine; said input-output model yields, in response to at least one input quantity u (Ix, Iy), a plurality of output quantities y (xa, ya, my, mz, ex, ey), which comprise, among other things, the position error (ex, ey) introduced in the measurement of position by the elastic deformations of parts of the machine (1) that undergo dynamic deformation; a step of definition of an estimator filter (M1) that yields, in response to measured values of input quantities u and, in response to measured values of a subset of the output quantities y, an estimate of the position error (ex, ey); the filter (M1) is obtained by means of an analytical method based upon the input-output model; and a step of continuous real-time reconstruction of the error, in which the measured values of the input quantities u and the measured values of a subset of the output quantities y are applied at input to said estimator filter (M1).

Abstract

A measuring machine (1) comprising a measuring column (10), which can move vertically with respect to a carriage (9), and a device (17) for balancing the weight of the column (10), which is provided with a pneumatic cylinder (18) having its liner (19) fixed to the column (10) and the stem (22) constrained to a supporting structure (12), carried by the carriage (9) via an elastic- suspension assembly (37) that enables the stem (22) to follow the liner (19) in the case of adhesion and to return into a position of equilibrium when the elastic reaction of the elastic-suspension assembly (37) overcomes the force of friction between the piston (21) and the liner (19); stick- slip phenomena are thus neutralized.
