Machining chatter has been studied by scholars over the past decades, since chatter has a
significant impact on surface quality and productivity. Researchers have carried out …

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 is a self-excited vibration phenomenon occurring in the cutting process, and the
onset of chatter will result in the worse machined surface and the redistribution of frequency …

Among the diverse challenges in machining processes, chatter has a significant detrimental
effect on surface quality and tool life, and it is a major limitation factor in achieving higher …

The train plug door is the only way for passengers getting on and off. Its failures will make
train operation ineffective. Taking the developed digital signal processing technologies into …

This paper presents a novel approach to detect the milling chatter based on Variational
Mode Decomposition (VMD) and energy entropy. VMD has already been employed in …

Intelligent spindles are core components of the next-generation of intelligent/smart machine
tools in the Industry 4.0 Era. The purpose of this paper is to clarify the concept of intelligent …

Abstract Variational Mode Decomposition (VMD) has attracted much attention and been
used to analyze different kinds of signals, such as mechanical signals, medical data, and …

Variational mode decomposition (VMD), an effective signal decomposing technique, has
attracted considerable attention in recent years. The successful applicability of the VMD …

Fault diagnosis methods based on dimensionless indicators have long been studied for
rotating machinery. However, traditional dimensionless indicators frequently suffer a low …
