ARTIS AE sensors (Acoustic Emission Sensors) measure high-frequency energy signals that are generated during material removal from the workpiece and the machine elements involved in the process. The acoustic emissions (also known as structural noise, depending on the medium in which they are propagated) are inaudible ultrasonic signals. The electrical signals measured in this way consist of characteristic frequencies and sound amplitudes that are specific to the cutting processes and can therefore be used for process monitoring.
The sensor signals are evaluated and visualized by the connected monitoring systems. Since even the smallest signal deviations are detected, they are best suited for applications that generate very small cutting forces where the level is very low. Therefore, the sensors are mainly used for break and wear detection of small tools, as well as for material contact, dressing and grinding processes. Often the integration is done optionally together with other sensors or sensorless solutions for ARTIS tool and process monitoring.
