Abstract

Die Erfindung betrifft ein Verfahren und eine Maschi­ ne zum CNC-gesteuerten Schleifen von Dekorflächen der dergleichen an relativ große Abweichungen von der Sollform aufweisenden Werkstücken aus Glas, wie Hohl­ gläser oder dergleichen, wobei das Schleifen jeder Dekorfläche in einem Vorschliff und mindestens einem Nachschliff erfolgt. Um dabei trotz der teilweise er­ heblich von der Sollform abweichenden Gläser gleich­ mäßige Dekorflächen zu erzielen, kann beim Vorschliff das Schleifwerkzeug (2) oder das Werkstück (11) bei Über­ schreiten eines vorwählbaren Schleifdruckgrenzwertes in Zustellrichtung, unabhängig von der Zustellein­ richtung zurückweichen. Dadurch auftretende Abwei­ chungen der Lage des Eingriffpunktes zwischen Werk­ zeug (2) und Werkstück (11) werden meßtechnisch erfaßt und in der Steuerung als beim Nachschliff, bei dem die Aus­ weichmöglichkeit des Schleifwerkzeugs (2) oder Werkstücks (11) dann blockiert wird, zu berücksichtigende Korrektur­ werte gespeichert. The invention relates to a method and a machine ne for CNC-controlled grinding of decorative surfaces the like to relatively large deviations from the Workpieces made of glass, such as hollow, having a predetermined shape glasses or the like, the grinding of each Decorative surface in a pre-sanding and at least one Regrinding takes place. To do so despite the partial he glasses deviating significantly from the target shape Achieving moderate decorative surfaces can be achieved with pre-sanding the grinding tool (2) or the workpiece (11) at over a preselectable grinding pressure limit in the infeed direction, regardless of the delivery back in the direction. The resulting divergence the position of the point of contact between the plant Stuff (2) and workpiece (11) are measured and in control than regrinding, where the off possibility of softening the grinding tool (2) or workpiece (11) then blocking correction to be considered values saved.
