Abstract: A monitoring module comprises a tool interface for holding the tool and a tool holding interface for insertion into a tool holder. The monitoring module has a sensor unit, whereby the axis of rotation of the monitoring module runs through the sensor unit. The sensor unit detects a variable representative of an acceleration in a plane normal to the axis of rotation of the monitoring module when the monitoring module rotates together with the tool/tool holder. A computing unit of the monitoring module receives the variables representative of the acceleration recorded by the sensor unit, determines a total acceleration from this, compares the total acceleration with a threshold value and determines that there is a concentricity error of the tool to be rotated, the monitoring module and/or the tool holder if the total acceleration is greater than the threshold value.

Abstract: A contactlessly or tactilely measuring measuring system having a multipurpose interface socket for accommodating and for connecting a contactlessly or tactilely measuring measuring device having a light transmitter and a light receiver, for determining the position of a tool or for determining the longest cutting edge of a rotating tool in a machine tool. The multipurpose interface socket has the following features: at least one mechanical stop, corresponding to a counterstop on the measuring device, for accommodating and repeatably placing the measuring device on the multipurpose interface socket; and at least one second fluid transfer point on the multipurpose interface socket, which corresponds to a first fluid transfer point on the measuring device.

Abstract: A contactlessly measuring system having a contactlessly measuring device, with a light transmitter portion and a light receiver portion, for determining the position of a tool or for determining the longest cutting edge of a rotating tool in a tool machine. A light barrier system is formed by the light transmitter portion and the light receiver portion, each being associated with a leg of an essentially U-shaped support structure of the measuring device. A fluid blowing device, associated with the measuring device, is provided for cleaning a tool to be measured, and/or a sealing air feed is provided in the area of a measuring beam of the measuring device designed as a light barrier measuring system, and/or a protective/closing device is provided at the light transmitter portion and/or the light receiver portion of the measuring device designed as a light barrier measuring system.
