Many completely new and important developments in technology and machining methods have made it necessary to update Machine Shop Practice, resulting in this second edition of the book. The revisions in this new edition are very thorough, incorporating the latest developments in numerically controlled machine tools; the introduction of SI metric units of measurement; and many other advances in shop practices. However, great emphasis is still placed on the operation of basic machine tools and the fundamentals related to their technology. Designed for use in the classroom or for home study, this book, with its many tables and formulas, is also useful in the workshop as a reference book for the more advanced craftsman, technician, and manufacturing engineer. Volume 2 is also available.
