Title
(EN) GRINDING METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL DE MEULAGE
Abstract
(EN)
In a method of and apparatus for grinding a cylindrical workpiece, the speed of the grinding wheel (14) and/or of the workpiece (18) is changed during the final dwell period in which sizing occurs, and the following additional steps are carried out: the rotational speed of the wheel and/or of the workpiece is measured, the target ratio of wheel speed to workpiece speed is calculated, and the speed of the wheel and/or workpiece is adjusted by a servo-controller (22) such that the desired ratio is altered to 0.25 if the mantissa of the target ratio is 0.5 or less, and if the mantissa is above 0.5, it is altered to 0.75.
(FR)
Dans le procédé et l'appareil décrits, qui servent au meulage d'une pièce cylindrique, la vitesse de la meule (14) et/ou de la pièce (18) est modifiée pendant la période d'arrêt momentané finale au cours de laquelle s'effectue le calibrage, et les étapes additionnelles suivantes sont réalisées: la vitesse de rotation de la meule et/ou de la pièce est mesurée, le rapport cible entre la vitesse de la meule et la vitesse de la pièce est calculé, et la vitesse de la meule et/ou de la pièce est réglée par un organe de servocommande (22), pour que le rapport désiré soit amené à 0,25, lorsque la mantisse du rapport cible est inférieure ou égale à 0,5, et, lorsque la mantisse est supérieure à 0,5, on fait passer le rapport désiré à 0,75.
