Title (EN) CONTROL PROCESS OF THE OPERATING CYCLE OF A FLUID PRESSURE MACHINE AND FLUID PRESSURE MACHINE WITH A FLUID CONTROL
(FR) PROCEDE DE COMMANDE DU CYCLE OPERATOIRE D"UNE MACHINE A PRESSION DE FLUIDE ET MACHINE A PRESSION DE FLUIDE AVEC COMMANDE A FLUIDE
Abstract: front page image
(EN)To increase the output of a fluid pressure machine and to obtain an economical operating cycle, the totality or a fraction of the travel of the machine tool-holder is measured completely or partially and is compared with the totality or fractions of an order travel. The differential value or values obtained are used, after analysis, in the form of control signals, for the control of the following travel of fraction or travel which is measured again. It is then compared with the overall or fraction of length of another order travel obtained by the differential value or values. The differential values obtained by this new comparison are used, after analysis, for controlling of the following travel, etc.
(FR)Pour accroitre le rendement d"une machine a pression de fluide et pour obtenir un cycle operatoire economique, on mesure la totalite ou une fraction de la course du porte-outil de la machine de facon complete ou partielle et on la compare avec la totalite ou avec des parties d"une course de consigne. La ou les valeurs de difference obtenues seront utilisees, apres analyse, sous forme de signaux de commande, pour la commande de la course ou fraction de course suivante, qui est mesuree de nouveau. On la compare ensuite avec la totalite ou la fraction d"une autre course de consigne obtenue par la ou les valeurs de difference. Les valeurs de difference obtenues par cette nouvelle comparaison sont utilisees, apres analyse, pour la commande de la course suivante, etc.
