Title (EN) LENS LATHE WITH VIBRATION CANCELLING ARRANGEMENT
(FR) TOUR A VERRES OPTIQUES A SYSTEME ANNULANT LES VIBRATIONS
Abstract: front page image
(EN)A method and apparatus for substantially nullifying vibration and deflection in a single point lens turning lathe (100) having a rapidly reciprocating lens cutting tool (114) and shuttle assembly. The apparatus includes three or more tool shuttles (108, 110, 112) of similar mass mounted for reciprocating movement along respective generally parallel shuttle paths. The shuttles (108, 110, 112) are reciprocally moveable by respective actuators (118, 120, 122) along their respective shuttle paths. The shuttle and tool assemblies are moved by their respective actuators (118, 120, 122) in opposite directions at a rate which causes forces generated by shuttle and tool assemblies moving in one direction to cancel forces arising from the shuttle and tool assembly movement in the opposite direction. Should an odd number of shuttle and tool assemblies be used, the amount of force generated by the mass moving in one direction may be compensated by having a different rate of movement, and hence a different stroke length from the mass moving in the opposite direction.
(FR)L'invention porte sur un procédé et un appareil annulant pratiquement les vibrations et les déflexions dans un tour (100) à verres optiques à arête unique muni d'un outil (114) de coupe à mouvement alternatif rapide et d'un système de navettes comportant au moins trois navettes (108, 110, 112) de même masse allant et venant sur autant de trajectoires sensiblement parallèles, et mues autant d'actionneurs (118, 120, 122). Les ensembles navette-outil commandés par leurs actionneurs respectifs (118, 120, 122) se déplacent dans des sens opposées à des vitesses telles que les forces engendrées par un ensemble allant dans un sens annulent les forces engendrées par un ensemble allant dans le sens opposé. Si on utilise un nombre impair d'ensembles, on peut compenser la force engendrée par la masse se déplaçant dans un sens en modifiant la vitesse et donc la course de la masse évoluant dans le sens opposé.
