In order to provide an operating method for a machine tool and to propose a system which enables the monitoring of the installation, position and the like of tools in a respective machine without the need for major construction work, the disclosure proposes a system for assigning tools mounted on rams to an installation position on a machine, which consists of a writable RFID chip with a transponder, memory and passive digital inputs positioned on the ram, and an electrically switchable contact panel positioned at a connection position of the machine, whereby the contacts of the contact panel can make contact with the digital inputs and the RFID chip transmits at least one identifier and the assignment of the digital inputs during a query process.

Machine tool

The invention relates to a device () for calibrating an underfloor wheelset lathe () without a calibration wheelset, comprising; a motor () with a rotational axis (D), a friction roller (), and a measuring bridge (), wherein the friction roller () is connected p a driveshaft of the motor (). The aim of the invention is to allow a simpler calibration without a calibration wheelset. This is achieved in that the friction roller () has an approximately cylindrical frictional surface with a defined nominal diameter. The invention additionally relates to an underfloor wheelset lathe () comprising such a device () and to a method for calibrating an underfloor wheelset lathe ().
