Method and apparatus for wear analysis on a machine tool

A device to control a machine tool with a plurality of working axes, the device comprising:

• a data memory;
• an input interface in communication with and adapted to receive position data from the data memory, the data memory storing, for at least one specific working axis of the plurality of working axes, a plurality of data tuples which each assign a load value to a position value relative to the specific working axis,
• a processor in communication with the input interface that selects, from the plurality of data tuples, a first data tuple having a first position value and a first load value and a second data tuple having a second position value and a second load value, the first position value being different from the second position value, the processing device further generating at least one control command for the machine tool, the control command instructing the machine tool to perform a first tolerance measurement at a first position described by the first position value and a second tolerance measurement at a second position described by the second position value, wherein on the basis of 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 determined and output;
• and
• an output interface coupled to the processing device that outputs the information about the wear of the part of the machine tool.
