This standard reference book for the mechanical industry is in use throughout the world. It makes available in clear, concise, ready-to0use form proven and accepted data and information needed by machine designers, shop management, skilled mechanics and students in engineering colleges, technical institutes and vocational schools. It contains 2,439 pages of engineering standards, mathematical tables, formulas and technical data. The HANDBOOK is an invaluable aid and working tool wherever anything mechanical is designed or constructed. Sections of the book cover: Mathematics, Mechanics & Strength of Materials, Machine Elements, Small Tools, Forming & Joining of Metals, Metal Cutting Tools & Procedures, Metals and their Heat treatment, Metal Finishing, Fastening, Hoisting, Measurements & Inspection, Allowances & Tolerances, Electric Motors.
The latest edition of the HANDBOOK combines all of the valuable features of earlier editions, including metric data and information, with the most recent and useful machine design and machine shop data taken from a wide variety of sources, many of which are not generally available to the individual reader. New and revised material has been added to the 21st Edition in the following subject areas: Plain Bearings, Rolling Element Bearings, Surface Grinding, Friction, Wire Measurements of Acme & Stub Acme Screw Threads Measurement of Relief Angles on Milling Cutters, Hole Coordinates, Machining Power, Balancing, Lathe Change Gears, Accuracy of Drilling Holes, Cutting Speeds & Feeds, and Trade Names for Tool Steels.
In accord with a continuing policy of making available material from the most recent standards essential data and information has been presented from the following new and revised American National Standards: Gages, Cap, Shoulder & Set Screws, Taps, Reamers, Pipe & Pipe Fittings, Screw Thread Terms, Acme & Stub Acme Threads, Retaining Rings, Surface Texture & Symbols, Standard Preferred Metric Limits & Fits, Precision Power Transmission Chains, Attachments & Sprockets, and NEMA Standards for Electric Motors.
The HANDBOOK has three difference indexes. Any one of the thousands of items in the various sections may readily be located by referring to the very complete general index. Subjects and topics are also cross-references wherever needed within the text. Quick access to all metric text and tables is provided by a separate metric index. A ready reference index on the inside covers makes it possible to locate important topics including formulas and tables.
I use this book EVERY day, it is sitting open on my desk right now as I type this; it is invaluable, and I find it so amusing to see it shelved on Goodreads, since it's not really the kind of book you sit down and read. (And yes I have the 25th edition, I made sure to shelve the one I own.)
Though I worked for twenty years as a technical writer, I’ll be the first to admit that I was never mechanically or technically inclined. I can write the best set of instructions you’ve ever seen, but watch me try to work on something mechanical, and you’ll see tools and expletives flying, the first time I run into a seemingly unsolvable problem. Sometimes I’ll, stick with the challenge until I solve the problem, but it takes so long.
So, why talk about the Machinery’s Handbook? After all, the book states right there on the title page that it’s “a reference book for the mechanical engineer, engineer, designer, manufacturing engineer, draftsman, toolmaker and machinist-” none of which I’ve ever aspired to be or had the first clue about.
Maybe my interest is due to working with engineers for so long; I grew to admire their intelligence and the way they were able to apply it in so many different situations. With some of them, the knowledge was acquired through years of schooling and experience. But for a few, the ability to problem-solve their way through a tough spot seemed instinctual. And while I was able to simplify their instructions so the user of a machine one of them designed was able to actually operate it, I nevertheless stood in awe of the abilities engineers and machinists possessed.
After seeing the results of their designs and fixes, I wondered where they went to for assistance. So it was that I started cracking open the MH, every so often. Curiosity played a role. My love of huge books was another. But more than that was the sense that I was looking into another world- one I could never function within, but still fascinating to watch.
As for the book, the edition I own measures 5″ x 7,” and since it’s over 2,500 pages long, it’s 2 1/2″ thick, giving it a box-like look. The first edition came out in 1914, and the tome’s continued use through the decades gives some credence to the claim that it is indeed “The Bible of the Mechanical Industries.” So much information is included in the chubby little book that a 249-page companion guide exists, filled with examples, solutions and test questions.
Want to learn about springs? There are fifty pages devoted to them. How about threads and threading? 230 pages. There are fifty-three pages on bearings, forty pages on heat treatment of steel, and forty-six pages on allowances and tolerances.
Of course, a book crammed with so much information would be unreadable were it not for the profuse amount of tables, charts, diagrams and illustrations. But even with the visual aids, there are certain topics that make my eyes glaze over, as interesting as they initially appear to be.
Amidst the chapter on formulas and geometry, there’s a section on calculation of circles within a circle. Say you’re trying to figure out how many burritos you could fit into a large tube. Assuming that you can’t just squish them in there- for that would be cheating, not to mention messy as hell- three factors have to be taken into consideration: the arrangement of the center or core burrito; diameter of enclosing burrito when outer layer of burritos is complete; diameter of enclosing burrito when outer layer is not complete. This is followed by “Table 1: Number of burritos contained in complete layers of burritos and diameter of enclosing burrito.” Then follows an uncomfortably large number of ugly-looking equations and another baffling table or two. And if that isn’t enough of a challenge, the next section shows how to fit burritos into a rectangle.
Since I’m in too deep to explain anything else about this amazing, confounding book, I’ll quit while I’m behind, and place the MH and its companion volume on the shelf, right next to the Stedman’s Medical Dictionary and an Engineering Drawing and Design book I’ve never used.
There is a lot of data in this book; including SI units and all the good stuff for machinists and detailed mechanical design. However it seems this book just keeps growing. It's not suitable for a student and unless you're on the machines or doing detailed design calculations everyday, it's a big waste of space. It's certainly misleading to call it a handbook and the mis-marketing is partly why the low rating. This thing is huge and expensive, not something you want to carry around, and also a little tricky to navigate to get to the specific data you might need. Well done to the contributors, but heads-up to anyone thinking of lugging this one around campus - don't! However the content is good for detailed machinery and mechanical design - particularly if you don't have the budget to buy all the industry standards.
A gorgeous, succinct almanac of vital lifeblood to the daily equip of any mechanical engineer worth their time and efficiency in gold. Bring bookmarks.
Indespensible, though most often used in shops for the thread minor/major tables. Lacks the metric equivalent and so subtracting one star for this glaring omission.
