Thread-Cutting Methods; A Treatise on the Operation and Use of Various Tools and Machines for Forming Screw Threads, Including the Application of ... Machines, and Thread-Rolling Machines

Ders Kitapları

The universal use of the screw thread, either as a fastening device or for transmitting motion from one part of a machine to another, combined with the numerous conditions under which it is used, has led to the development of many different kinds of tools and machines for forming screw threads. These tools vary from the hand-operated tap or die to the specialized semiautomatic and fully automatic machines capable of threading duplicate parts with considerable rapidity. While much has been published on thread-cutting practice, most of this material has been of a miscellaneous character, and there is evidently need for a general treatise covering the various machines and auxiliary equipment used for this important branch of machine shop work. The purpose of this treatise is not only to describe all the important types of tools, machines, and methods which have been developed for producing external and internal screw threads, but to show the relation between the different processes. If the screw thread problem were merely to determine how to cut a thread of the required size, pitch, and accuracy, it would, in most cases, be relatively simple, but like other manufacturing problems, it is usually complicated by the fact that the work must be done on a commercial basis. The various methods of forming screw threads are familiar to practically all machinists and machine shop foremen, but comparatively few know to what general class of work each method is best adapted. While it is often difficult to decide this question, an understanding of the reasons why different types of threading tools and machines were originated and the kind of work for which they are generally used will at least simplify the problem greatly.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten Books is a publisher of historical writings, such as: Philosophy, Classics, Science,
