Audiobook Modern Machine-Shop Practice, Volumes I and II

This authoritative two-volume work provides a thorough examination of modern machine-shop operations, focusing heavily on the geometry and mechanics of gear-wheel teeth. The author explores epicycloidal and involute curves, explaining how gear teeth must be formed to transmit uniform velocity and power without excessive friction or wear. Detailed attention is given to the design and application of generating circles, the phenomena of sliding and rolling motion, and the prevention of tooth interference in both spur and internal gears. Beyond gear design, the text covers screw-thread standards, fastening devices, and the complete construction and operation of engine lathes, including slide rests, driving work, and cutting tools. The work extends into advanced measuring machines, shaping and planing operations, and specialized drilling and tapping machinery. Throughout the text, the author relies on practical workshop experience rather than higher mathematics, utilizing arithmetical rules and over three thousand engravings to illustrate approved industrial methods.
