Fundamentals of Milling
Like turning, milling is a process with a geometrically defined
cutting edge. The rotating 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 passing frequencies
