Machine-shop MathematicsGinn, 1922 - 162 σελίδες "This work has been prepared to meet the needs of students who expect to become machinists, either in the special line of automobile construction or in the more general lines of the machine shop. It is therefore strictly limited in scope to the needs of those who are entering upon this kind of work, and it treats only of such topics as experience has shown are demanded by the practical machinist who is determined to advance in his vocation."--Preface. |

Σελίδα 35 - PITCH AND LEAD OF SCREW THREAD. The terms " pitch " and " lead " of screw threads are often confused. The pitch of a screw thread is the distance from the center of one thread to the center of the next thread, whether the screw has a single, double, triple, or quadruple thread.
Σελίδα 9 - ... nickel. Tungsten and chromium in particular give the steel the property of retaining its cutting ability under very high speeds or heat. Cutting Speed. — Cutting speed is the velocity with which a cutting tool engages the work and is always given in feet per minute (fpm). The term feet per minute has somewhat different meanings for different machines. In turning work on a lathe it means the number of linear feet, measured on the surface of the work, which passes the edge of a cutting tool in...
