Since the first edition published more than 100 years ago, Machinery’s Handbook has been the most popular engineering resource of all time. Universally considered the principal reference in the manufacturing and mechanical industries, the Handbook is the ultimate collectionof essential, critical information needed by engineers, designers, drafters, metalworkers, toolmakers, machinists, educators, students, and serious home hobbyists. From engineering and design departments, machine and metalworking shops, and a wide range of manufacturing and industrial facilities, to countless classrooms and workshops around the globe, this 32nd Edition of the Machinery’s Handbook is the must-have technical reference.New, Revised, and Expanded in the 32nd Edition:Additive Manufacturing: Cutting-edge information on 3D printing materials, techniques, and workflow, with an expanded list of international standards addressing this rapidly evolving manufacturing segment.Dimensioning and Measuring: Reworked explanations and instructions for calibrating, applying, and reading inch and metric verniers, dial and digital calipers, and inside, outside, and screw thread micrometers. Refined formulas for calculating tolerances.Fasteners, Threads, and Threading: Definitive standard specifications for numerous screw threads, bolts, other fasteners, nuts and washers, tap and clearance drills have been verified and updated across the board, with revised and new tables and figures.Machine Elements: Expanded sections detail drive couplings, shaft alignment methods, and friction and lubrication challenges, with an entirely new section on regulated food grade machine lubricants. Revised and new rolling element bearings text and tables explain types, functionality, and features, with additional figures.Metalworking and Manufacturing: New expert coverage with detailed illustrations addresses commonly used metalworking dies, design, and selection, along with related processes and applications for sheet metalworking. Improvements in the welding section include pipe welding positioning.Part Design and Production: Updates encompass the latest in CNC programming, CAD/CAM operations, and other design and production processes. New to this edition is CNC machining of carbon-fiber reinforced polymers, plus discussions of shop-floor programming, simulation for pre-production process verification, feature-based machining, and computer-aided modeling optimization.Properties and Selection of Materials: Legacy elements and modern-day plastics data have been revised, with new information on embodied energy of materials, supply chain cost and carbon footprint calculations, recycling and reclamation considerations, and polymer composite structures and production methods.

Amply illustrated and deeply detailed, this classic guide details the creation of grades of steel via heat treatments. It offers fascinating insight into metal manufacturing processes.Since this guidebook was published in 1914, it carries a certain historic value; at the time, the United States economy was undergoing industrialization. Steel was in high demand, and the technology behind its manufacture was improved upon greatly. The metal's importance could not be understated; the expanding rail networks, new multistory constructions, plus tools and factory machines all required huge quantities of quality metal. As we learn, steel is not a simple product: various grades must be achieved via subtle variations in the heat and techniques applied during its manufacture.To articulate his points, the author appends over ninety charts and diagrams of equipment. Together these show how the furnaces work, and how the hardness of the metal is varied to meet strict specifications. Certain intense processes receive their own chapter, such as steel for machine tools and the use of the electric furnace, plus alloys and the testing of the finished products. For its breadth of detail and superb understanding, Erik Oberg's work remains readable over a century since its original publication.

Together with number theory, geometry and analysis, algebra is one of the very cornerstones of modern mathematics. Broadly speaking, it is the study of mathematical symbols and the laws for manipulating them using formulas. This vintage book contains an introductory guide to the subject, walking the reader through its basics and moving on to its practical uses in electrical and steam engineering drawing, as well as machine design and workshop practice Contents include: "Use of Formulas", "Use of Equations in Solving Problems", "Principles in Algebra", "Solving Equations of the First Degree", "Solving Quadratic Equations", etc. This volume will be of utility to those with an interest in engineering, and it would make for a wonderful addition to allied collections. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.

First published in 1914, this volume contains a detailed treatise on two different types of gear: worm gears and spiral gears. A worm gear refers to a gear where a worm (a gear in the form of a screw) meshes with a worm gear (similar in appearance to a spur gear). A spiral gear is a type of bevel gear that contains helical teeth. Written in clear, simple language and containing useful diagrams and tables, this volume will prove to be an invaluable resource for anyone with an interest in the design and construction of gearing. Contents include: "Principal Rules and Formulas for Designing Spiral Gears", "Formulas for Special Cases of Spiral Gear Design", "Herringbone Gears", "Methods for Forming the Teeth of Spiral and Herringbone Gears and Worms", "Hobs for Spur and Spiral Gears", "Calculating The Dimensions of Worm Gears", "Allowable Load and Efficiency of Worm Gears", "The Design of Self-Locking Worm-Gears", etc. Many vintage books such as this are increasingly scarce and expensive.

"Screw Thread Cutting" is a vintage guide to "threading", which refers to the process of creating screw threads. More screw threads are produced each year than any other machine component, and there are many methods of creating threads, including subtractive methods (cutting and grinding); deformative or transformative methods (rolling and forming; moulding and casting), and additive methods (such as 3D printing). This volume focuses on subtracting and transformative methods, making it a useful reference guide for those with an interest in traditional methods of making screws. Contents include: "Change Gears for Thread Cutting, by Erik Oberg", "Kinks and Suggestions in Thread Cutting", and "Tables and Formulas for Making Thread Tools, by A. L. Valentine, Erik Oberg, and Jos. M. Stabel". Many vintage books such as this are increasingly scarce and expensive.
