Basics Of Precision Engineering

Advances in engineering precision have tracked with technological progress for hundreds of years. Over the last few decades, precision engineering has been the specific focus of research on an international scale. The outcome of this effort has been the establishment of a broad range of engineering principles and techniques that form the foundation of precision design. Today’s precision manufacturing machines and measuring instruments represent highly specialised processes that combine deterministic engineering with metrology. Spanning a broad range of technology applications, precision engineering principles frequently bring together scientific ideas drawn from mechanics, materials, optics, electronics, control, thermo-mechanics, dynamics, and software engineering. This book provides a collection of these principles in a single source. Each topic is presented at a level suitable for both undergraduate students and precision engineers in the field. Also included is a wealth of references and example problems to consolidate ideas, and help guide the interested reader to more advanced literature on specific implementations.

The Key Words In Manufacturing Are Cost And Quality. While This Has Been Generally True Throughout The History Of Manufacturing, We Have Today Entered Into A Highly Competitive Stage Where Quality Has Assumed Overwhelming Importance. There Is No Survival Without It. Quality ``Just Does Not Happen, It Is Caused``. Quality Circles, Total Quality, Iso 9000, Etc. Are Some Measures To Improve Quality.The Broad Purpose Of The Present Book Is To Explain The Concept Of Part Accuracy And Machine Tool Accuracy And The Interaction Between Them. It Considers In Detail The Influence Of Various Factors Affecting Accuracy. The Factors Considered Are Stiffness, Vibrations, Thermal Effects, Tool Wear, Geometrical Inaccuracy Inherent In The Machine Tools Themselves, Cutting Conditions, Location And Others. The Interaction Of Dimensions In A Chain Of Machining Processes Is Also Included. The Standards Relevant To Accuracy Are Explained. Processes To Obtain Precision Parts Are Described. The Treatment Is Not Just Descriptive. Analytical Expressions And Numerical Examples Are Included. The Scope Of The Book Is Novel And The Subject Matter Will Be Highly Useful Not Only To An Academic In The Area Of Manufacturing But Also To An Engineer On The Shop Floor.

“Another gem from one of the world’s justly celebrated historians specializing in unusual and always fascinating subjects and people.” — Booklist (starred review) The revered New York Times bestselling author traces the development of technology from the Industrial Age to the Digital Age to explore the single component crucial to advancement—precision—in a superb history that is both an homage and a warning for our future. The rise of manufacturing could not have happened without an attention to precision. At the dawn of the Industrial Revolution in eighteenth-century England, standards of measurement were established, giving way to the development of machine tools—machines that make machines. Eventually, the application of precision tools and methods resulted in the creation and mass production of items from guns and glass to mirrors, lenses, and cameras—and eventually gave way to further breakthroughs, including gene splicing, microchips, and the Hadron Collider. Simon Winchester takes us back to origins of the Industrial Age, to England where he introduces the scientific minds that helped usher in modern production: John Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. It was Thomas Jefferson who later exported their discoveries to the fledgling United States, setting the nation on its course to become a manufacturing titan. Winchester moves forward through time, to today’s cutting-edge developments occurring around the world, from America to Western Europe to Asia. As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?

This book is a comprehensive engineering exploration of all the aspects of precision machine design—both component and system design considerations for precision machines. It addresses both theoretical analysis and practical implementation providing many real-world design case studies as well as numerous examples of existing components and their characteristics. Fast becoming a classic, this book includes examples of analysis techniques, along with the philosophy of the solution method. It explores the physics of errors in machines and how such knowledge can be used to build an error budget for a machine, how error budgets can be used to design more accurate machines.
