Abstract
The present disclosure relates to a machine tool, in particular a grinding machine, and to a method for measuring a workpiece, in particular a workpiece diameter, in a machine tool, in particular a grinding machine, which comprises a workpiece mount, a tool unit, a measuring device and a control device which is connectable to the measuring device and the tool unit, wherein the measuring device is accommodated on the tool unit and comprises at least two measuring probes, wherein in a measuring configuration the at least two measuring probes are spaced apart by a basic spacing which defines a measurement region, wherein the basic spacing is selected to be greater than a known reference dimension, wherein the control device is configured for acquiring values detected by way of the at least two measuring probes, of detecting an actual position of the tool unit, and, on the basis of a displacement path of the tool unit when probing a workpiece which is moved into the measurement region, of determining an actual spacing, in particular an actual diameter, with consideration to the reference dimension and/or the basic spacing.
