If a stationary Dynamometer is used, then this will be mounted
on the machine table while the workpiece is installed on the Dynamometer.
In order to reduce the mass on the Dynamometer
and thus to reduce the negative influence on the dynamics of the
Dynamometer, the workpiece is screwed directly to the Dynamo
meter, thus making it possible to dispense with the heavy and
often non-rigid collet chuck. The active force Fa that is in effect
at the work level can be calculated in simple steps from the
feeding force and the normal feeding force.
