A method for automatic wear correction for the machining of a workpiece by means of a rotating grinding tool in a cnc - controlled machine tool

摘要

The present invention relates to a method for automatic wear correction for the machining of a workpiece 1 by means of a rotating grinding tool 2 in a cnc - controlled machine tool, wherein a working area 3 of the grinding tool 2, starting from an apical end 4 of the grinding tool 2, into a plurality of annular zones 5 is divided by to the axis of rotation 6 vertical planes, it being possible by means of a machining program contact points b of the grinding tool 2, which during the machining with the workpiece 1, be determined, whereby the contact points b the zones 5 are assigned, wherein the resulting for the respective zones 5 intervention time is determined, wherein a wear behavior of the grinding tool 2 for the respective zones 5 is determined in advance, whereby as a function of the respective intervention time a wear value of the grinding tool 2 is determined, and wherein on the basis of the wear value for compensating for a dimensional change of the grinding tool 2, a correction value of the cnc - control is determined.
