Sensorised Tool Holders for Monitoring the Process Forces During High-Speed Internal Grinding

The application of sensor technology for monitoring and analysing manufacturing processes is becoming increasingly important and is well established for manufacturing processes with geometrically defined cutting edges. However, in grinding processes such as internal grinding, the use of sensor-based tool holders reaches its limits. Especially in these demanding processes, the use of sensor technology offers a high potential for increasing manufacturing accuracy, performance and process reliability. In this context, a demonstrator of a tool holder for high-speed applications with integrated measurement technology has been developed. In experimental investigations, the tool holder has been qualified for internal grinding processes. It has been possible to perform reliable high-speed internal grinding processes even at high tool speeds of up to 30,000 1/min.
