Abstract:
(EN) The invention relates to a method for fine machining a cylindrical workpiece surface (16) of a workpiece blank (14) by means of a fine machining tool (26). Said method comprising the following steps: generating a relative rotational movement (nW) between a tool (26) and a workpiece blank (14) about a machining axis (18) which is concentric to a cylindrical workpiece surface (16) of the workpiece blank (14); generating a relative feed rate (vW; vF) between the tool (26) and the workpiece blank (14) along the machining axis (18); detecting an actual value (TPIST; FPIST) of a process variable (TP; FP), which is a function of a relative force between the tool (26) and the workpiece blank (14) and which can assume a plurality of process variable values; and continuously controlling the process variable (TP; FP) by changing the relative feed rate (vW, vF) in such a way that the more the relative feed rate (vW; vF) changes, the more the actual value (TPIST; FPIST) of the process variable deviates from a desired value (TPSOLL; FPSOLL) of the process variable (TP; FP).
(FR) L'invention concerne un procédé de finition d'une surface de pièce cylindrique (16) d'une ébauche de pièce (14) au moyen d'un outil de finition (26). Le procédé comprend les étapes suivantes : générer une rotation relative (nW) entre un outil (26) et une ébauche de pièce (14) sur un axe d'usinage (18) concentrique à une surface de pièce cylindrique (16) de l'ébauche de pièce (14); générer une vitesse d'avance relative (vW; vF) entre l'outil (26) et l'ébauche de pièce (14) le long de l'axe d'usinage (18); détecter une valeur réelle (TPIST; FPIST) d'une grandeur de processus (TP; FP) représentant une fonction d'une force relative entre l'outil (26) et l'ébauche de pièce (14) et pouvant prendre une pluralité de valeurs de grandeur de processus; et réguler en continu la grandeur de processus (TP; FP) par modification de la vitesse d'avance relative (vW, vF)) de sorte que plus la vitesse d'avance (vW; vF) varie d'autant plus que la valeur réelle (TPIST; FPIST) de la grandeur de processus s'écarte d'un valeur de consigne (TPSOLL; F{SOLL) de la grandeur de processus (TP; FP).
(DE) Verfahren zur Feinbearbeitung einer zylindrischen Werkstückfläche (16) eines Werkstückrohlings (14) mittels eines Feinbearbeitungswerkzeuges (26), mit den Schritten: Erzeugen einer Relativrotation (nW) zwischen einem Werkzeug (26) und einem Werkstückrohling (14) um eine Bearbeitungsachse (18) herum, die konzentrisch ist zu einer zylindrischen Werkstückfläche (16) des Werkstückrohlings (14); Erzeugen einer relativen Vorschubgeschwindigkeit (vW; vF) zwischen dem Werkzeug (26) und dem Werkstückrohling (14) entlang der Bearbeitungsachse (18); Erfassen eines Istwertes (TPIST; FPIST) einer Prozessgröße (TP; FP), die eine Funktion einer Relativkraft zwischen dem Werkzeug (26) und dem Werkstückrohling (14) ist und die eine Vielzahl von Prozessgrößenwerten annehmen kann; und stetiges Regeln der Prozessgröße (TP; FP) durch Verändern der relativen Vorschubgeschwindigkeit (vW, vF), derart, dass die relative Vorschubgeschwindigkeit (vW; vF) sich umso mehr ändert, je mehr der Istwert (TPIST; FPIST) der Prozessgröße von einem Sollwert (TPSOLL; FPSOLL) der Prozessgröße (TP; FP) abweicht.
