Abstract
A system for chip-removing machining of a workpiece and for measuring and evaluating force and torque during the chip-removing machining of the workpiece includes a machine tool with a tool for chip-removing machining of the workpiece; a device for measuring force and torque that includes a plurality of piezoelectric transducers generating polarization charges being communicated through a respective measuring channel; and a stationary evaluation unit for evaluating measured value data of the device. The device includes a measuring unit installed in the machine tool and rotates with the tool about an axis of rotation during chip-removing machining. The device includes a control unit that transmits measured values as measured value data in a wireless manner directly to the evaluation unit with a transmission power in the range of 0.1 mW to 10 mW.
