In most modern metal shops, you’ll find both a lathe and a vertical mill. Both machines function by removing material from a block of metal—the "workpiece." The key difference between the two is how the workpiece is handled. On a lathe, the workpiece rotates, and is cut away by a knife tool. (Typical products of lathe work are "turned parts" such as spindles, bearings, screws, washers, and circular blanks for gears.)          On a milling machine, it’s the cutter that rotates. The workpiece is clamped to a table that is moved by precise amounts in two axes at right angles. (Typical mill products are flat-surfaced blocks of metal, like a cube, sometimes drilled for spindles or dowel pins, often tapped for screws.)           Both the lathe and mill are incredibly flexible machines, but neither is capable of doing useful work right "out of the box." Both call for a number of accessories for holding the workpiece, as well as a selection of different cutting tools, drills, reamers, etc. Unlike lathe turning, which has not changed fundamentally in the past 100 years, milling in the small shop has been changed radically by the recent introduction of bench-top machines.          There are now so many different milling machines that insider information has become even more important. In this work, Choosing & Using the Right Milling Machine, Richard Rex provides everything needed to choose the right type of mill—knee-type (Bridgeport) or bench-top—and properly install it depending on the type of work you’re doing. With suggestions for finding, installing, and using the essential accessories, including digital readouts, this work is a must-have for model shops around the globe. And it’s the perfect companion work to Choosing & Using the Right Metal Shop Lathe.             Features Covers different types of milling cutters, including end mills, drill bits, reamers, and slitting saws.Introduces information on the add-ons that get a shop operational with the least delay and expense.Instructs on the installation and use of three popular accessories—table power-feed, digital readout (DRO), and rotary table.Provides a workpiece tutorial that demonstrates many of the commonplace milling routines—ideal for first-time users.

Ductility and Formability of Metals: A Metallurgical Engineering Perspective uses metallurgical, mechanical and physical principles and concepts to explain ductility while emphasizing the influence of material microstructure on damage mechanisms. Focusing on steel, aluminum, copper, titanium and magnesium alloys, the book examines the strain hardening behaviors of these metals and alloys, the influence of strain rate and temperature, and ductile fracture mechanics. Hot plastic deformation is covered with special consideration given to its interplay with recrystallization phenomena. Other phenomena such as Dynamic Strain Ageing (DSA) and Adiabatic Shear Banding (ASB) are discussed, and metal working applications such as forging, extrusion and machining are included throughout. Methods for control of ductile cracks in metal parts resulting from rolling, forging, extrusion, drawing, and sheet metal forming are also outlined.

A celebrated international bestseller that exposes the ticking time-bomb underneath our new technological order.The resources race is on. Powering our digital lives and green technologies are some of the Earth's most precious metals - but they are running out. And what will happen when they do? The green-tech revolution will reduce our reliance on nuclear power, coal, and oil, but by breaking free of fossil fuels, we are setting ourselves up for a new dependence - on rare metals like cobalt, gold, and palladium. These are essential to electric vehicles, wind turbines, and solar panels, as well as our smartphones, computers, tablets, and other technologies. But we know very little about how rare metals are mined and traded, or their environmental, economic, and geopolitical costs - until now.

The progress of civilization can be, in part, attributed to their ability to employ metallurgy. This book is an introduction to multiple facets of physical metallurgy, materials science, and engineering. As all metals are crystalline in structure, it focuses attention on these structures and how the formation of these crystals are responsible for certain aspects of the material's chemical and physical behaviour. Concepts in Physical Metallurgy also discusses the mechanical properties of metals, the theory of alloys, and physical metallurgy of ferrous and non-ferrous alloys.

Metal-organic frameworks (MOFs) are crystalline porous materials constructed from metal ions/clusters and organic linkers, combining the merits of both organic and inorganic components. Due to high porosity, rich functionalities, well-defined open channels and diverse structures, MOFs show great potentials in field such as gas storage and separation, catalysis, and sensing. Combining them with polymers tunes their chemical, mechanical, electrical and optical properties, and endows MOFs with processability. Covalent organic frameworks (COFs) are crystalline porous materials built from organic molecular units with diverse structures and applications. Hybrid materials with intriguing properties can be achieved by appropriate preparation methods and careful selection of MOFs/COFs and polymers, broadening their potential applications. This book documents the latest research progress in MOF/COF-polymer hybrid materials and reviews and summarises hybridization strategies to achieve MOF/COF polymeric composites. It also introduces various applications and potential applicable scenarios of hybrid MOF/COF polymers. Hybrid Metal-Organic Framework and Covalent Organic Framework Polymers offers an overview to readers who are new to this field, and will appeal to graduate students and researchers working on porous materials, polymers, hybrid materials, and supramolecular chemistry.

Investing in a new metalworking lathe is a big step for any shop (especially home shops), where there’s usually no one around to help. Once the lathe is up and running, you should theoretically be able to make the special items you previously did without (or paid through the nose for), such as shafts, plain, tapered or threaded discs, bearings, and so on. But if you are new to this, you’ll want to know a lot more than you can learn from the salesman or the manual. Does the lathe really match your needs, and if so, how much?Choosing & Using the Right Metal Shop Lathe is an essential source of information for lathe buyers and users at every level, from mini-size tabletops up to industrial machines weighing half a ton or more. It answers the question of what else you will need to get useful work from the machine. For instance, what comes as "standard equipment" with the lathe? Most include a chuck (usually a 4-jaw independent, not the self-centering 3-jaw you’ll want to use most of the time), maybe a faceplate (rarely used), and a 4-way toolholder you will probably swap right away for a more sensible design. Never included is a tailstock drill chuck, an essential accessory you will need from day one—and the same goes for actual cutting tools. Almost certainly, there won’t be a digital readout (DRO), which used to be regarded as a "maybe-someday" luxury—but not anymore.The work talks about cutting oils, cutting speeds and easier-to-machine materials, and it cautions against buying sets of anything, vs. buying the one accessory you’ll truly need. Finally, there are chapters on building a tailstock drill press, a special toolpost for easy screw cutting, and a precision grinder for lathe tools that can be made from oddments of material in a couple of days or less.           Features Differentiates between the truly essential features (screw-cutting) and the nice-to-have (power feeding), spindle speed selection from a gearbox (typical) or continuously variable (more convenient).Offers advice on screw-cutting US and metric threads, and handling the machinist’s most trouble-prone actions, such as knurling and parting off.Provides a workpiece tutorial that demonstrates many of the commonplace lathe routines—ideal for first-time users.
