Book Description
The cutting edges on engineering tools must lie at precise angles to ensure effective cutting, and sharpening must recreate the original geometry of each tool. This book provides an understanding of what is involved in sharpening typical lathe, milling, drilling and threading tools. With over 550 photographs and illustrations this new book covers sharpening techniques for the most commonly used engineering tools, screwdrivers and gravers, lathe, milling, reaming, drilling and threading cutters. It identifies the two principal types of workhead, and discusses the ways in which their geometry affects typical sharpening setups. It teaches how to use the three basic movements of swing, tilt and rotate to position a tool against a grinding wheel to ensure correct tool angles and sharp cutting edges. Contains useful tables for setting cutting and clearance angles and provides general advice on tool and cutter grinders, and includes examples of the use of workholders to suit a range of tools. Includes information on abrasive materials and the types and shapes of grinding wheel suitable for use on a tool and cutter grinder. Finally, it shows photos of accessories that can be made to simplify setups, including workheads, toolholders and fixtures used to hold circular saws, parting tools and dies, as well as an angle gauge to quickly set clearance angles on reamers and milling cutters.

Book Description
The Great Lakes ecosystem is recognised by many as an international natural resource that has been altered by human activities and climate variability. These alterations have led to degraded water quality, diminished habitat, lower native fish and wildlife populations, and an altered ecosystem. In response, the federal governments of the United States and Canada and the state and provincial governments in the Great Lakes basin are implementing several restoration activities. These activities range from mitigating the harmful effects of toxic substances in lake waters to restoring fish habitat. This books provides the reader with a background on and issues of the Great Lakes restoration initiative, as well as the action plan for the years 2010-2014.
