Abstract: A method of controlling a machine tool comprising the steps of: providing a data memory containing, for at least one specific working axis of the plurality of working axes, a plurality of data tuples each assigning a load value to a position value relative to the specific working axis, selecting a first data tuple and a second data tuple whose load values are different, and generating at least one control command for the machine tool, wherein the control command is adapted to perform a first tolerance measurement at a first position value and a second tolerance measurement at a second position value, and wherein, based on a first result of the first tolerance measurement and a second result of the second tolerance measurement, information about wear of a part of the machine tool is output. A corresponding device is also be disclosed.

Abstract: Device for detecting highly stressed positions in a machining tool with a spindle head and a spindle motor, the device comprising: a measuring unit adapted to acquire measurement values of the spindle head during operation of the spindle unit, the measurement values having a current position of the spindle head; a memory unit adapted to store the measurement values acquired; a stress determining unit adapted to determine an associated stress value for each of the detected positions taking into account the measurement values; and an output unit adapted to at least one of outputting the detected positions with the respective associated stress value, and determining from a total number of the determined stress values at least one high stress value which is greater than the other stress values of the total number, and then outputting the at least one determined high stress value with the position assigned to it.
