Like turning, milling is a process with a geometrically determined
cutting edge. The rotary and usually multi-cutting edge tool performs
the cutting movement while the feed movement, depending
on the type of construction of the machine tool, is carried out
by either the spindle head or the machine table. The cut is interrupted,
i.e. the cutting edge of the tool is not engaged during the
entire rotation. Because of the changing chip thickness and the
varying number of cutting edges currently engaged, the forces
are also changing constantly. This means that the Dynamometer
is subjected to extremely strong dynamic loads. Particularly with
milling, the high natural frequencies of the piezoelectric Dynamometers
are a decisive advantage for obtaining high-quality signals
despite high tooth meshing frequencies
