Abstract

A method for the compensation of measurement errors of a measuring machine (1) comprising a probe (13) provided with a first body (14) and a mobile part comprising a second body (16), which is attached to the first body (14) and is movable with respect to the first body (14), and a stylus (18) having at least one tip (19) at one end configured to cooperate with a workpiece (20); the method comprising the steps of:- providing a mathematical model of the probe (13);- acquiring a first signal (P̈1) related to the acceleration of the first body (14);- acquiring a second signal (P0-P1) related to the relative displacement between the first and second bodies (14, 16); and- estimating a deformation of the probe (13) by means of a state observer (25), which uses said mathematical model and receives as input the first signal (P̈1) and the second signal (P0-P1) .
