Motor Drive for Machine Tools


Book Description

Excerpt from Motor Drive for Machine Tools: With a Chapter on Wiring for Motor-Driven Machinery Just here it may be well to point out one of the greatest advantages of the motor drive. It will be noticed that the belt drive, which gave a range of 75 to 580 revolutions, did so in five steps varying by at least 60 per cent per step. If the lathe is running on, let us say, the fourth step it may be found that the cutting speed, owing to the size of the work or the condition of the tool, is not as high as could be used to best advantage. To jump to the next speed, however, increases the cutting speed over 60 per cent, which will be too much.

Machine Tools and Workshop Practice for Engineering Students and Apprentices (Classic Reprint)


Book Description

Excerpt from Machine Tools and Workshop Practice for Engineering Students and Apprentices The next essential is a thorough grip of the principles under ]ying the action of modern machine tools, and of the methods employed to standardise and specialise work. For instance, the tendency is to use the lathe largely as a roughing-out machine, whilst the grinding machine, along with limit-gauges for standard size of interchangeable parts, takes the place of the fitter, except in general work. Working to limit-gauges is found to be less expensive than using single accurate gauges, and further reduces the cost of erection of the parts of a machine.

Studies in the History of Machine Tools


Book Description

This work was originally published as four separate books; their titles, and reviewers' comments, are given below: History of the Gear-Cutting Machine: A Historical Study in Geometry and Machines "The book represents an overwhelmingly well-done job of reducing a great mass of material—scholarly references, patents, catalogs, engineering and trade journals, and machines themselves—into a logical story of development. Written with zest and relish, this vivid account presents a wealth of unusual information. The illustrations are particularly good, for many of them come from previously untapped sources." —Technology and Culture History of the Grinding Machine: A Historical Study in Tools and Precision Production "From the polished artifacts of prehistoric times Mr. Woodbury traces the development of methods, abrasives, and the machine tools which interdependently contributed to the advanced grinding techniques used today. Many fine illustrations." —The Tool Engineer History of the Milling Machine: A Study in Technical Development "Mr. Woodbury traces the evolution of milling machines from Eli Whitney's machine (circa 1820), the first miller ever built, to numerical controlled milling machines.... presented cleanly with ample detail. Fine illustration and complete bibliography are provided." —The Tool Engineer History of the Lathe to 1850: A Study in the Growth of a Technical Element of an Industrial Economy "Woodbury, who teaches the history of technology at the Massachusetts Institute of Technology, is at work on a history of machine design which promises to alter our perspectives not only in his special field but in general cultural history.... His present history of the lathe (to about 1850) absorbs the entire previous literature and goes far beyond it." —Lynn White, Jr.




Machine Blacksmithing (Classic Reprint)


Book Description

Excerpt from Machine Blacksmithing It is not necessary that a system for the blacksmith shop be of the kind usually known as red tape, which often takes more time to handle than the time it saves; but a simple method of keeping track of work, tools, and material will save time and expense. To begin with, the blacksmith shop ought to be large enough to pro vide a place for everything in the shape of tools and equipment, and permit everything to be in its place. Forges should be numbered with figures of size and color which can be easily seen from any part of the shop. The forges should be referred to by their numbers, instead of so-and-so's forge. This would insure work being taken to the place for which it was intended. With each forge there ought to be a tool bench of such size and design as would accommodate one full set of blacksmith's tools of the kind used at the anvil. Each tool should be marked with its size and the number of the forge to which it belongs, so that each blacksmith will know the tools which form part of the set he is supposed to use, even if they should in any way get mixed up with others. To insure keeping a full set at each forge, it would be well to give each man a list of the tools belonging to the forge at which he is expected to work, with the understanding that he will be held responsi ble for all tools not worn out or accidentally broken. If any tool is worn out or broken it should be reported to the man in charge, so that it could be replaced as soon as possible. Having a full equipment at each forge would be a decided advantage to a new man starting in to work, because, as anyone who has ever been employed in a black smith shop knows, as soon as a blacksmith leaves the shop in which he has been working, he is no sooner gone than there is a raid upon the tools he used, and it usually takes but a short time to have them exchanged for the poorest tools in the shop, or, perhaps, just removed without any attempt at replacing. When a new man comes along, he is heavily handicapped, having the worst tools in the place with which to work, and it sometimes takes weeks before he has a chance of show ing what he can do.
