The self-excited vibration, called chatter, is one of the main limitations in metal removal
processes. Chatter may spoil the surface of the part and can also cause large reduction in …

Chatter is a self-excited vibration of parts in machining systems. It is widely present across a
range of cutting processes, and has an impact upon both efficiency and quality in production …

Chatter vibrations are present in almost all cutting operations and they are major obstacles
in achieving desired productivity. Regenerative chatter is the most detrimental to any …

This paper presents a discrete-time modeling of dynamic milling systems. End mills with
arbitrary geometry are divided into differential elements along the cutter axis. Variable pitch …

Studies on ploughing mechanism were separately treated for static and dynamic cutting
processes in the literature. In this paper, a generalized method, which is suitable for …

This paper provides a novel approach for identifying the process damping directly from
chatter-free milling tests. First, power spectrum density matrix of cutter's deflections is …

The stability of milling process dominated by multiple modes was traditionally predicted in
the time domain by only selecting the most flexible mode. This paper theoretically studies …

Existing ploughing mechanism and velocity-dependent mechanism, which were used for
explaining the process damping in milling, did not consider the feedback influence of …

Process damping significantly improves the machining stability in the low speed cutting
process. Just because of this, it plays an important role in the avoidance of chatter vibrations …

Accurately obtaining dynamical parameters in relation to machining processes is extremely
crucial to predict stability lobe diagrams (SLDs), which are used to plan chatter-free cutting …
