Title
(EN) COORDINATE MEASURING MACHINE WITH CONSTRAINED COUNTERWEIGHT
(FR) MACHINE DE MESURE DE COORDONNÉES AVEC CONTREPOIDS SOUS CONTRAINTE
Abstract
(EN) A coordinate measuring machine has a measuring member for measuring a workpiece, a counterweight to control movement of the measuring member, and a pulley and cable system coupling the measuring member with the counterweight. The coordinate measuring machine also has a guide track, where the counterweight is movably secured to the guide track. The guide track substantially limits counterweight movement, relative to the measuring member, to one dimension.
(FR) La présente invention concerne une machine de mesure de coordonnées comportant un organe de mesure pour la mesure d'une pièce à travailler, un contrepoids pour le contrôle du mouvement de l'organe de mesure, et un système de poulie et de câble reliant l'organe de mesure au contrepoids. La machine de mesure de coordonnées comporte également un rail de guidage, le contrepoids étant fixé de manière amovible au rail de guidage. Le rail de guidage limite sensiblement le déplacement du contrepoids, par rapport à l'organe de mesure, à une dimension.
