Book Description
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 Description
Metal cutting is widely used in producing manufactured products. The technology has advanced considerably along with new materials, computers and sensors. This new edition considers the scientific principles of metal cutting and their practical application to manufacturing problems. It begins with metal cutting mechanics, principles of vibration and experimental modal analysis applied to solving shop floor problems. There is in-depth coverage of chatter vibrations, a problem experienced daily by manufacturing engineers. Programming, design and automation of CNC (computer numerical control) machine tools, NC (numerical control) programming and CAD/CAM technology are discussed. The text also covers the selection of drive actuators, feedback sensors, modelling and control of feed drives, the design of real time trajectory generation and interpolation algorithms and CNC-oriented error analysis in detail. Each chapter includes examples drawn from industry, design projects and homework problems. This is ideal for advanced undergraduate and graduate students and also practising engineers.

Book Description
As we move further into the 21st century, despite the fact that new technologies have emerged, machining remains the key operation to achieve high productivity and precision for high-added value parts in several sectors, but recent advances in computer applications should close the gap between simulations and industrial practices. This book, “Machining Dynamics and Parameters Process Optimization”, is oriented toward the different strategies and paths when it comes to increasing productivity and reliability in metal removal processes. The topics include the dynamic characterization of machine tools, experimental dampening techniques, and optimization algorithms combined with signal monitoring.
