Presently, the service performance of new-generation high-tech equipment is directly
affected by the manufacturing quality of complex thin-walled components. A high-efficiency …

The general trend towards lightweight components and stronger but difficult to machine
materials leads to a higher probability of vibrations in machining systems. Amongst them …

The time needed to exchange information in the physical world induces a delay term when
the respective system is modeled by differential equations. Time delays are hence …

We study mechanical vibrations in milling with non-uniform pitch and variable helix tools.
The process is modeled by a periodic delay differential equation with distributed delay …

Chatter is still one of the most challenging problems in machining vibrations. Researchers
have focused their efforts to prevent, avoid or reduce chatter vibrations by introducing more …

In this paper, we deal with the control of a transport partial differential equation/nonlinear
ordinary differential equation (PDE/nonlinear ODE) cascade system in which the transport …

Chatter is more likely to occur during the turning process of a thin-walled cylindrical
workpiece owing to the low rigidity of such workpieces. Chatter causes intensive vibration …

A type of chaos called laminar chaos was found in singularly perturbed dynamical systems
with periodic time-varying delay [Phys. Rev. Lett. 120, 084102 (2018)] 0031-9007 …

Seeking a higher level of automation, according to Intelligent Manufacturing paradigm, an
optimal process control for milling process has been developed, aiming at optimizing a multi …

Milling chatter is a harmful phenomenon, which seriously affects the quality of the workpiece
and limits the processing efficiency. The milling with variable spindle speed is an effective …
