Beschreibung
Zusammenfassung:	A method for automatically compensating short-term relative thermal transient deformation of the cross rail of a gantry machining device includes the steps of measuring the horizontal expansion of the cross rail, measuring the horizontal expansion of the bed, and determining the difference between the two measurements to determine a compensation amount. L'invention porte sur un procédé de compensation automatique d'une déformation transitoire thermique relative à court terme de la traverse porte-outil d'un dispositif d'usinage sur portique, lequel procédé comprend les étapes consistant à mesurer la dilatation horizontale de la traverse porte-outil, à mesurer la dilatation horizontale du lit, et à déterminer la différence entre les deux mesures afin de déterminer une quantité de compensation.
