Active vibration control for chatter suppression
38th Structures, Structural Dynamics, and Materials Conference, 1997The vibration absorber, in its various forms, is a well-known control strategy that reduces the forced vibratory response of structures by introducing a carefully tuned, auxiliary degree of freedom. The method is simple, effective, and widely used.

Chatter suppression with multiple time-varying parameters in turning
Journal of Materials Processing Technology, 1999Abstract This paper presents a new method, multiple time-varying parameter (MTVP) turning for chatter suppression. Compared to the single time-varying parameter (STVP) turning, the new method uses both time-varying spindle speed and time-varying rake angle to suppress chatter.

Chattering suppression methods in sliding mode control systems
Annual Reviews in Control, 2007Abstract The implementation of sliding mode control is often irritated by high frequency oscillations known as “chattering” in system outputs issued by dynamics from actuators and sensors ignored in system modeling. This paper provides analysis of chattering in such systems with unmodeled based on the Lyapunov theory and the describing function ...

Magnetostrictive Actuator for Chatter Vibration Suppression of Boring Bar
2018 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2018Boring is a machining process to manufacture the hole. During the deep hole process, boring bar with a high aspect ratio is easy to chatter under various cutting conditions, and it causes poor surface roughness and dimensional error. This paper aims to develop a new magnetostrictive actuator to suppress the chatter vibration of a high aspect ratio ...

Chatter Suppression with Piezoelectric Film for Microstructure Surface Structuring
2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018Micro-structure surface is widely used in optics and industry due to their excellent properties, such as optical properties, wear resistance, adhesion and lubricity. The current Micro-structure surface manufacturing is mainly ultra-precision cutting. In the process of Micro-structure surface manufacturing, excessive spindle speed or depth of cut may ...

Analysis and suppression of chatter in robotic machining process
2007 International Conference on Control, Automation and Systems, 2007One of the most challenging issues in robotic machining process is to know the vibration/chatter characteristics. To reduce the trial and error frustration, this paper presents the underline mechanism and theoretical analysis to provide physical understanding for the onset of chatter problem and principles to prevent that.

Sliding mode reaching laws for suppressing chattering
2008 27th Chinese Control Conference, 2008Beginning with the reasons of chattering, this article proposes two new sliding mode reaching laws. In one hand, they guarantee the system reach the switching surface rapidly and remain on it, in another hand, they suppress or weaken the chattering effectively, such that the system response can better realize the unification of rapidity and stability ...

A fuzzy system for chatter suppression in end milling
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2004This paper reports a fuzzy logic approach for chatter suppression in end milling processes. Vibration energy and the peak value of a vibration frequency spectrum are jointly used as chatter indicators and inputs to the proposed fuzzy controller. The outputs of the fuzzy controller are the altered machining parameters for chatter suppression.

Proposal of ‘accelerative cutting’ for suppression of regenerative chatter
CIRP Annals, 2018Abstract A novel speed variation method, namely ‘accelerative cutting’, is proposed for suppression of regenerative chatter in short-duration plunge cutting, e.g. finishing of sealing, seating, and bearing surfaces. Although the cutting time is short in these processes, the large cutting width often causes chatter.
