CRC | 1st Edition | 2005 | Pages: 1872 pages | ISBN: 0849315808 | PDF | 23.2Mb

Vibration and shock are ubiquitous phenomena, and a modern, practical reference for the field is overdue. This impressive new Vibration and Shock Handbook provides a thoroughly up-to-date, convenient, and authoritative reference on the techniques, tools, and data relevant to the modeling, analysis, design, instrumentation, and control of vibration, shock, noise, and acoustics. In 45 chapters contributed by professionals in current practice, the book covers both the theoretical and the practical aspects, including the use of MATLAB® toolboxes and LabVIEW® tools. It provides a wealth of examples and case studies and presents all of the material in a format that is ideal for easy reference and recollection.

Understanding Mastercam

mastercam

by Jon Stenerson, Kelly Curran

Prentice Hall | ISBN: 0130205818 | 2002 | DJvu | 251 pages | 4.5 Mb

This practical, easy-to-use and understand book guides users through a logical, step-by-step approach to learning Mastercam. It evolves from a keystroke by keystroke process to an exploration of programming and post processing programs for the mill. Chapter topics cover Mastercam’s working environment, an overview of the Mastercam CAD/CAM process, creating basic geometry, creating and modifying existing geometry, tooling fundamentals, creating 2D tool paths in Mastercam mill, creating lathe geometry, creating tool paths in Mastercam lathe, and importing CAD files.

Once again Curran and Stenerson have succeeded in delivering a practical text that is easier to understand and follow than reference manuals. This textbook is reader friendly, offering plenty of exercises as well as step-by-step procedures with clear explanations. The exercises are designed to reinforce the skills for programming and operating CNC equipment using Mastercam, the leading software program in the machine tool industry.
Features of this edition:

* Organized so instructors can adjust their presentations for varying levels of proficiency from beginner through experienced operator.
* Includes a chapter devoted to creating and modifying basic geometry.
* Covers the basic background concepts in a manufacturing environment and then proceeds to advanced techniques.

Handbook of Power Quality

power-quality

Due to the complexity of power systems combined with other factors such as increasing susceptibility of equipment, power quality (PQ) is apt to waver. With electricity in growing demand, low PQ is on the rise and becoming notoriously difficult to remedy. It is an issue that confronts professionals on a daily basis, but few have the required knowledge to diagnose and solve these problems.

Handbook of Power Quality examines the full panorama of PQ disturbances, with background theory and guidelines on measurement procedures and problem solving. It uses the perspectives of both power suppliers and electricity users, with contributions from experts in all aspects of PQ supplying a vital balance of scientific and practical information on the following:
frequency variations;
the characteristics of voltage, including dips, fluctuations and flicker;
the continuity and reliability of electricity supply, its structure, appliances and equipment;
the relationship of PQ with power systems, distributed generation, and the electricity market;
the monitoring and cost of poor PQ;
rational use of energy.

The accompanying website hosts case studies for each chapter, demonstrating PQ practice; how problems are identified, analysed and resolved. The website also includes extensive appendices listing the current standards, mathematical formulas, and principles of electrical circuits that are critical for the optimization of solutions.

This comprehensive handbook explains PQ methodology with a hands-on approach that makes it essential for all practising power systems engineers and researchers. It simultaneously acts as a reference for electrical engineers and technical managers who meet with power quality issues and would like to further their knowledge in this area.
