Sensorized cutting tool

A cutting tool comprising:

• a cutting tool body including at least one seat arranged for receiving a cartridge or a cutting insert, wherein the seat includes at least one support surface;
• clamping means arranged for securing the cartridge or cutting insert in the seat, wherein the tool body includes a sensor retaining structure adjoining the support surface;
• and
• a piezo sensor is arranged in the sensor retaining structure, wherein the piezo sensor is an elastically deformable piezo sensor, which has a central longitudinal axis and a main direction of sensitivity perpendicular to the central longitudinal axis, the piezo sensor including a measuring section, along which the central longitudinal axis is substantially parallel to the support surface, and wherein the piezo sensor is elastically deformed in the sensor retaining structure to a pre-stressed initial state and deformable to a plurality of further stressed measuring states.
