The invention relates to a tool holder () which is embodied for rotation around a tool holder rotation axis (D) and which comprises at its one axial longitudinal end () a tool segment () for receiving a tool, and at its other axial longitudinal end () a coupling segment () for torque-transferring coupling to a machine tool (), a measurement apparatus () for sensing data relating to the operation of the tool holder () being provided on the tool holder (), which apparatus encompasses at least the following components:&#x2014;at least one sensor () supplying a sensed signal;&#x2014;a signal transfer apparatus () for transferring a measured signal;&#x2014;an electrical circuit () connected in signal-transferring fashion to the sensor () and to the signal transfer apparatus (); and&#x2014;an energy supply apparatus () that is connected to the signal transfer apparatus () and to the electrical circuit (). According to the present invention the tool holder () comprises a tool holder main body () that comprises both the tool segment () and the coupling segment (), at least one component from among the sensor (), electrical circuit (), and energy supply apparatus () being received in a recess () in the interior of the tool holder main body ().

Tool holder with integrated sensor system

A method for producing a housing structure at least partially enclosing at least one component, wherein the housing structure is produced with a construction process utilizing at least one of repeated layered deposition and solidification of material, which is interrupted at least once before completion of the housing structure, and during at least one interruption at least one component, which is not produced by the construction process, is joined to or disposed in a partially finished housing structure, and the construction process is then continued after the interruption until the housing is completed, wherein at least one of an actuator and sensor comprising at least partially a transformer material selected as the at least one component to be joined to or disposed in the housing structure.
