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 Stability in the Dynamics of Metal Cutting written by S.T. Chiriacescu and published by Elsevier. This book was released on 2013-10-22 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous models have been proposed for the study of the dynamic behaviour of cutting tools. An analysis of the main works published over the past 20 years reveal a lack of general methodology in the mathematical modelling of the dynamic cutting process (CP) and in the elastic structure (ES), as well as the absence of efficient and general methods for identifying the conditions under which the amplitudes of the vibration chatter between tool and workpiece can become problematic.This book provides a thorough review on the mathematical modelling and stability analysis of the dynamic machining system, presenting solutions for the practical problems that can be encountered. The practical points of the stability and instability of the DMS are discussed, together with various aspects of the modelling and identification of the CP and ES systems. The latest findings are examined in the context of a general study using matrix equations. Such a study on the matrix method is timely in view of the rapid spread in the use of mini and micro-computers.Based on the matrix equations of the CP and ES systems, the general equations of the DMS with time-invariant parameters are established, and various procedures for the actual stability analysis of this system are presented. Many examples are accompanied by illustrations which also provide adequate practical instructions for other problems in the stability analysis of the DMS. The last part of the book deals with the modelling and stability analysis of the DMS with time-varying parameters, random parameters and random input. The work is addressed primarily to those interested in the design and exploitation of machine tools in both industry and research. It will also be of interest to applied mathematicians, and can be used as a reference book for advanced courses in mechanical engineering.

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.
