Analysis of chatter suppression in vibration cutting

International Journal of Machine Tools and Manufacture, 2002
Abstract The occurrence of chatter is strongly influenced by the tool geometry in conventional cutting. Therefore, the tool geometry is regarded as a very important factor. On the other hand, it is known that vibration cutting is capable of cutting hardened steels. However, the theoretical explanation for finish hard-cutting with vibration cutting is

Chatter Vibration of Lathe Tools

Journal of Fluids Engineering, 1956
Abstract This paper deals with a chatter vibration which occurs frequently when metals are being machined. It has been ascertained experimentally that the chatter is a self-excited vibration caused by the lag in fluctuation taking place in the horizontal cutting force behind the horizontal vibration of the work.

A review of chatter vibration research in turning

International Journal of Machine Tools and Manufacture, 2012
Abstract 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 process as it creates excessive vibration between the tool and the workpiece, resulting in a poor surface finish, high-pitch noise and accelerated tool wear which ...

Detection of the onset of chatter vibration

Journal of Sound and Vibration, 1986
In a flexible manufacturing system or a fully automated machining system, the computer control system of the machine tools must be able to recognize and control the cutting states, particularly the unwanted ones. Chatter vibration being one of them, its onset needs to be detected.

Simulation of Chatter Vibrations in Reaming

Volume 3: Design and Manufacturing, 2007
A time domain approach is used to study the cutting conditions in reaming process that leads the system to regenerative chatter vibrations. The dynamic analysis of the system includes inertia of the tool, centripetal and Coriolis terms, damping and the first mode bending of reamer. A model of cutting forces proportional to chip cross sectional area and

Suppression of Chatter Vibration in Drilling

Journal of Manufacturing Science and Engineering, 1998
In this study, from the viewpoint of suppressing chatter vibration in drilling, the effects of cutting conditions on the initiation boundary of chatter vibration were investigated experimentally. Furthermore, the application of an impact damper on drills was attempted to suppress chatter vibrations.

The Modulation of Chatter Vibrations

Journal of Engineering for Industry, 1969
The results of several experimental investigations concerning the nature of machining chatter are discussed. They indicate that chatter vibrations are generally amplitude modulated and that the chatter frequency may or may not vary from the free vibrational frequency of the chattering component.

Simulation of Chatter Vibrations for Wiper Systems

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">An experimental investigation is first carried out to analyze the influence of the geometrical configuration of a wiper system on the chattering occurrence. The measurement results show a combined influence of the load applied on the rubber blade and the attack angle on the vibratory level of the blade.

Chatter vibrations of high-performance motorcycles

Vehicle System Dynamics, 2013
Motorcycle racing teams occasionally experience speed-limiting vibrations of around 25 Hz frequency in mid-corner. The nature of the vibrations has not been closely defined yet and the mechanics are currently not properly understood. Conventional motorcycle-dynamics models are shown here to reveal the existence of a vibration mode that aligns with the ...

The development of frequency and amplitude of chatter vibration

International Journal of Machine Tools and Manufacture, 1989
Abstract This paper deals with the analysis of regenerative chatter vibration. The assumptions and results of conventional stability analysis are discussed. The mechanism of a self-excited vibration frequency development process and its influence on vibration amplitude is studied.
