A tool post of a machine tool, in which the tool post is capable of receiving a cutting insert for machining a component, is provided. The tool post includes at least one sensor capable of determining a parameter representative of a cutting action between a component to be machined and a cutting insert; and a support housing which is electrically connected to the sensor and includes a battery and a printed circuit board supplied with current by the battery. The printed circuit board supports, at least partially, a radio transmission unit. The housing includes a base and a cover which can be detached from one another. The battery is supported by the cover and the printed circuit board by the base or vice versa.

Instrumented tool post, and associated tool holder

The invention relates to an insert holder for a tool for turning a machine tool, comprising an insert holder body (), the head () of which is intended to receive a cutting insert (), characterized in that at least two measurement recesses () are provided in the insert holder body () on the side of the head (), said measurement recesses () being arranged symmetrically relative to the neutral fiber () of the insert holder body () and centered on the neutral fiber (). The measurement recesses () have, respectively, a planar bottom () that is parallel to the direction (Y) of the component of the tangential cutting force of the insert holder to be measured, and parallel to the longitudinal direction (X, Z) of the insert holder body (). The insert holder also comprises at least one first strain gauge () configured such as to measure the change in shape of the planar bottom () of at least one of the measurement recesses ().
