Download or read book Control of Cutting Vibration and Machining Instability written by C. Steve Suh and published by John Wiley & Sons. This book was released on 2013-08-01 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents new developments on machine tool vibration control based on discontinuous dynamical systems Machining instability is a topical area, and there are a wide range of publications that cover the topic. However, many of these previous studies have started by assuming that the behavior of the system can be linearised. Meanwhile, there are many recent advances in the fields of signal processing, nonlinear dynamics, and nonlinear control, all of which are relevant to the machining stability problem. This book establishes the fundamentals of cutting mechanics and machine tool dynamics in the simultaneous time-frequency domain. The new nonlinear control theory developed by the authors that facilitates simultaneous control of vibration amplitude in the time-domain and spectral response in the frequency-domain provides the foundation for the development of a controller architecture universally viable for the control of dynamic instability including bifurcation and chaos. Once parameters underlying the coupling, interaction, and evolution of different cutting states and between the tool and workpiece are established, they can then be incorporated into the architecture to create a control methodology that mitigate machining instability and enable robust, chatter-free machine tool design applicable in particular to high speed micro- and nano-machining. Presents new developments on machine tool vibration control based on discontinuous dynamical systems Provides a clear and concise approach to the understanding and control of machine tool and workpiece vibrations from an alternative view, contributing to an in-depth understanding of cutting dynamics and robust control of machining instability Equips the reader with the knowledge to understand the dynamics of cutting and operation of machine-tool systems in different conditions as well as the concept of cutting instability control Includes data examples in MATLAB coding

Download or read book Machine Tool Structures written by F. Koenigsberger and published by Elsevier. This book was released on 2016-01-21 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machine Tool Structures, Volume 1 deals with fundamental theories and calculation methods for machine tool structures. Experimental investigations into stiffness are discussed, along with the application of the results to the design of machine tool structures. Topics covered range from static and dynamic stiffness to chatter in metal cutting, stability in machine tools, and deformations of machine tool structures. This volume is divided into three sections and opens with a discussion on stiffness specifications and the effect of stiffness on the behavior of the machine under forced vibration conditions. The following chapters explore the stability of the machine structure against chatter; methods of stability analysis; tests and principles of dampers; chatter during grinding operations; and stresses and deformations of closed box structures subjected to bending and shear. Calculation methods for determining stiffness constants of a structure's individual parts, as well as methods for determining the resulting stiffnesses, modal shapes, and their parameters, are also described. The final chapter presents systematic procedures for the analysis of machine tool structures. This book is intended for university students, research workers, and designers.
Download or read book Sources and Control of Mechanical Vibrations Affecting Machine Tool Performance Quality written by Alfred Otto Schmidt and published by . This book was released on 1965 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the internal and external sources of vibration in machining operations which impair the performance quality of conventional machine tools was conducted. Particular attention was give to the surface finish of workpieces and the deflection of specific machine tool components. A literature survey on machine tool vibrations was abstrated. All experimental work was carried out under such operating conditions as can be found in an average precision machine shop. The measuring instruments used were standard items except in the case of a special surface analyzer. Sources of mechanical vibrations in machine tools can be determined satisfactorily with limited instrumentation but a thorough understanding of machine tool functions and metal cutting technology is necessary. Forced and self-excited vibrations can occur simultaneously with both having a detrimental effect upon surface finish and dimensions. (Author).
Download or read book Control of Forced Vibration in Machine Tool metal Cutting Systems written by Theodore R. Comstock and published by . This book was released on 1967 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is engaged in a program of research which is directed at the study of the mechanism of forced vibrations in machine tool-metal cutting systems. Analytical methods, test and specification techniques have been developed that should significantly aid machine tool manufacturers in the design of essentially vibration-free machine tools for given cutting operations. The types of disturbances which cause forced vibrations in machine tools are described and categorized. The detrimental effects upon performances, which these disturbances have during cutting operations, are discussed. An attempt is made to show that the problem of forced vibrations in metal cutting systems can be generalized and simplified to a very large extent. The analytical methods to be used in this general approach are developed, and the experimental results obtained therefrom are discussed. In order to accomplish the objectives of this program the study of the mechanism of forced vibrations was divided into two main areas. The first of these areas is concerned with the effects of forced vibration due to variations in cutting depth and disturbances from internal and external forces. The remaining phase of this program is concerned with the effects of forced vibration caused by the transmission of forces through the foundation. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An Engineering Research Series title. One of the remarkable achievements of modern manufacturing techniques is the ability to achieve nano-metre surface finishes. Ultraprecision machining based on single-point diamond turning (SPDT) is a very important technique in the manufacture of high-precision components where surface finish is critical. Complex optical surfaces, for example, can be produced without the need for post-machining polishing. This book focuses on the aspect of modelling nano-surface generation in ultra precision SPDT. Potential industrial applications in the prediction of surface quality, the process optimization, and precision mould manufacturing are also studies. The essential differences between single-point diamond turning and conventional machining are described. The history and technology of single-point diamond turning are presented and single chapters emphasize the related metrology and cutting mechanics. Important aspects of surface generation are also discussed. Features of the text are the sound approach, systematic mathematical modelling, and computer-aided simulation of surface generation in the development of surfaces exhibiting nano-surface qualities. TOPICS COVERED INCLUDE: Fundamentals of ultra-precision diamond turning technology Cutting mechanics and analysis of microcutting force variation Mechanisms of surface generation Characterization and modelling of nano-surface generation Computer-aided simulation of nano-surface generation Diamond turning of aspheric optics. Based upon the extensive experience of the authors Surface Generation in Ultra-precision Diamond Turning: Modelling and Practices will be of interest to engineers, scientists, and postgraduate students.
