Rotating dynamometers (RCD) to measure cutting forces ...

In machining processes, everything is geared to boosting productivity. A rotating dynamometer (RCD) is a diagnostic tool that is inserted directly into the machine tool's spindle. When an RCD is used, the cutting forces that act on the edge are measured directly on the rotating tool – even when the machining processes are highly complex.
