Wireless rotating cutting force dynamometers, Fz max. 20 kN, Mz max. 100 Nm / 9170B

The complete measuring system comprises a sensory tool holder (Rotating Cutting Force Dynamometer) which can be mounted directly on the machine spindle and a communication box that wirelessly receives the data from the tool holder. The spindle type on the machine tool determines which rotor version is required. The piezoelectric 4-component sensor, four charge amplifiers and the digital transmission electronics are integrated into the tool holder. It measures the radial forces Fx and Fy, the axial force Fz and the torque Mz. For highest measurement quality, each channel has four measuring ranges to adapt the measurement setup during finishing operations or rough machining. In order to do that, the receiver box has an Ethernet connection. The setup of the parameters and the data transfer to a PC can be done through that same connection. Furthermore, the system has a remote input for starting and stopping the measurements. To connect the system to analog inputs of machine controllers, the box has analog 10 V outputs. This allows a wide range of setups from laboratory to fully automated machine integration. The software for this is the PTS (Piezo Tool System) App. This software enables systematic data recording and analysis. Adjustable analysis templates allow large quantities of measurement data to be easily and quickly viewed and evaluated in batch analyses.
