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.

Development of a machining monitoring and chatter suppression device

2018 IEEE Industrial Cyber-Physical Systems (ICPS), 2018
A cyber-physical system that can automatically monitor the chatter of a machine tool and adjust the machining parameters to suppress the chatter is in need in the industry. For the CNC machine tools without network connection capability, to implement such a cyber-physical system is difficult.

Machining Chatter Suppression

2015
This chapter presents a systematic stability analysis of spindle speed variation (SSV) method for machining chatter suppression based on a machining chatter model of nonlinear delay differential equation. The theoretical results are verified by results of numerical simulations and experiments.

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 Suppression via an Oscillating Cutter

Manufacturing Science and Engineering: Volume 2, 1997
Abstract Chatter is one of the critical issues in a machining process since it deteriorates the surface quality of a workpiece and reduces machining efficiency. A new method is developed to suppress chatter in which an oscillating cutter is used to machine the workpiece through a stepping motor and a transmission mechanism so as to vary ...

Adaptive Feedforward Chatter Suppression in Machining

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">This paper presents a novel approach for active, on-line suppression of chatter in machining operations. The presence of chatter limits the material removal rate and therefore, lowers the productivity of machining processes.

Chatter suppression in milling with anisotropic tools

2009 International Symposium on Micro-NanoMechatronics and Human Science, 2009
Chatter vibration in milling often results in poor surface finish and rapid tool wear, consequently limiting productivity. Thus, chatter suppression is one of the most important themes in industry. Self-excited chatter vibration in milling is generally caused by two kinds of mechanisms, i.e., regeneration and mode-coupling, and both mechanisms should ...

Chatter Suppression in Milling: An Active Approach

Dynamic Systems and Control, 1999
Abstract A new approach to chatter control in milling is presented in this paper. The proof-of-concept control system comprises a tool holder, analog and digital control electronics, and power amplifiers to drive the actuator elements.

Chatter suppression by adaptive speed modulation

International Journal of Machine Tools and Manufacture, 1997
In this paper a PD fuzzy logic controller is designed and implemented to suppress chatter in peripheral milling. The controller selects combinations of the amplitude and frequency of spindle speed modulation, online, to keep a chatter indicator, the R-value, close to a prescribed set point.

In-process detection and suppression of chatter in milling

International Journal of Machine Tools and Manufacture, 1992
Abstract The use of a continuously variable spindle speed as a means of suppressing chatter in milling is investigated. A digital simulation model for dynamic milling is presented. The model includes runout, process damping and stiffness contributed by flank interference with and without tool wear, and spindle speed variation.
