Author Description

For everyone who wants to read and interpret engineering drawings accurately, this book offers practical, tested guidance. Thoroughly up-to-date, it uses new drafting conventions resulting from the latest production techniques. In addition, it is timely in its anticipation of the adoption and implementation in this country of the metric system of measurement. To assist you in metric conversion, that system is used exclusively in all applicable areas. In 49 carefully sequenced units you get es¬sential information on interpretation, dimen¬sioning, machining symbols, not-to-scale di¬mensions, countersinks, counterbores, and spotfaces, tolerances and allowances, metric threads, first-angle projection, arrowless di¬mensioning, steel specifications, broken-out and partial sections including sectioning of webs, phantom outlines, roller element bear¬ings, geometrical tolerancing, and datums for tolerancing by position. Dozens of special assignments aid your un-derstanding of the material by involving you in actual work situations. These assignments range in scope from sketching and dimension¬ing to problems involving counter clamp bars, feed hoppers, base plates, compound rest slides, couplings, shaft supports, rack details, terminal blocks, crossbars, spark adjusters, base assembly, orientation tolerancing, and profiles of lines and surfaces. To assist you in solving these assignments, as well as every other conceivable problem, 22 handy tables and charts have been compiled from numerous handbooks and catalogs. They include data in the following areas: conversion of fractions of an inch to millimeters, ISO metric threads, number and letter size drills, sheet metal gauges and thicknesses, square and flat stock keys, hexagon head bolts (regular series), locational transition fits, and conversion factors.
