Variable pitch milling cutters intend to
increase performance, but off-the-shelf cutters do not ensure this generally.
Depending on the milling process they are selected for, they can perform better
or even worse than uniform pitch cutters do. Improved performance can be
guaranteed by considering the reflected dynamic behaviour of the machine/tool/workpiece
system.
This work presents the achievable upper and lower capability bounds by
introducing so-called stabilizability diagrams of a hypothetical variable pitch
milling cutter that is tuned continuously along the stability boundaries.
Robustly tuned milling cutters are designed for selected spindle speed ranges,
which are experimentally tested both under laboratory and industrial conditions
