Abstract

Ein Verfahren zur Überwachung eines Schleifprozesses, bei welchem ein Werkstück in einer Bandschleifmaschine geschliffen wird,
wobei die Bandschleifmaschine über einen Schleifkopf verfügt, welcher eine Kontaktwalze und/oder einen Schleifschuh sowie zumindest eine Umlenkrolle umfasst,
wobei ein Schleifband von der zumindest einen Umlenkrolle oder gemeinsam von der zumindest einen Umlenkrolle und der Kontaktwalze geführt wird,
wobei die Bandschleifmaschine über eine verfügt, um das Werkstück während des Schleifprozesses relativ zum Schleifkopf zu bewegen,
wobei das Schleifband während des Schleifens durch die Kontaktwalze und/oder durch den Schleifschuh auf eine Oberfläche des Werkstücks gedrückt wird,
wobei der Bandschleifmaschine ferner eine Sensoreinheit zur Abtastung der Oberfläche des Werkstücks zugeordnet ist, welche mit einer Auswerteeinheit in Verbindung steht,
soll dadurch gekennzeichnet sein, dass
die Sensoreinheit die Oberfläche des Werkstücks nach dem Schleifen abtastet, wobei die Sensoreinheit und die Auswerteeinheit dazu eingerichtet sind, ein Vorhandensein zumindest einer Rattermarke zu erfassen.A method for monitoring a grinding process in which a workpiece is ground in a belt grinder,
wherein the belt grinding machine has a grinding head which comprises a contact roller and / or a sanding shoe and at least one deflection roller,
wherein an abrasive belt is guided by the at least one deflection roller or together by the at least one deflection roller and the contact roller,
wherein the belt grinder has one to move the workpiece relative to the grinding head during the grinding process,
wherein the abrasive belt is pressed onto a surface of the workpiece during grinding by the contact roller and / or by the abrasive shoe,
wherein the belt grinding machine is further assigned a sensor unit for scanning the surface of the workpiece, which communicates with an evaluation unit,
should be characterized in that
the sensor unit scans the surface of the workpiece after grinding, wherein the sensor unit and the evaluation unit are adapted to detect a presence of at least one chatter mark.
