Title
(EN) METHOD OF GRINDING A WORKPIECE HAVING A CYLINDRICAL BEARING SURFACE AND METHOD FOR DETERMINING PROCESSING PARAMETERS
(FR) PROCÉDÉ DE MEULAGE D'UNE PIÈCE À TRAVAILLER AYANT UNE SURFACE DE PORTÉE CYLINDRIQUE ET PROCÉDÉ POUR DÉTERMINER DES PARAMÈTRES DE TRAITEMENT
Abstract
(EN) A method for grinding a workpiece by means of a grinding wheel is disclosed. The workpiece comprises a cylindrical bearing surface (3), a radially extending sidewall (4) extending outward from the cylindrical bearing surface, and a curved transition portion (5) connecting the cylindrical bearing surface with the sidewall. During grinding, the feed in an increment is selected so as to achieve a pre-set maximum surface temperature of the workpiece at a point of the grinding wheel resulting in the highest surface temperature of the workpiece. Furthermore, a method for determining processing parameters for such a grinding method is disclosed.
(FR) L'invention concerne un procédé de meulage d'une pièce à travailler à l'aide d'une roue de meulage. La pièce à travailler comprend une surface de portée cylindrique (3), une paroi latérale s'étendant radialement (4) s'étendant vers l'extérieur à partir de la surface de portée cylindrique, et une partie de transition incurvée (5) reliant la surface de portée cylindrique à la paroi latérale. Pendant le meulage, l'avance par un incrément est sélectionnée de façon à obtenir une température de surface maximale pré-établie de la pièce à travailler en un point de la roue de meulage ayant comme conséquence la température de surface la plus élevée de la pièce à travailler. L'invention concerne également un procédé pour déterminer des paramètres de traitement pour un tel procédé de meulage.
