Synopsis
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 esŽsential information on interpretation, dimenŽsioning, machining symbols, not-to-scale diŽmensions, countersinks, counterbores, and spotfaces, tolerances and allowances, metric threads, first-angle projection, arrowless diŽmensioning, steel specifications, broken-out and partial sections including sectioning of webs, phantom outlines, roller element bearŽings, 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 dimensionŽing 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.
About the Author
Cecil H. Jensen took an early retirement from teaching to devote his full time to technical writing. He held the position of Technical Director at the McLaughlin Collegiate and Vocational Institute, Oshawa, Ontario, Canada, and has more than twenty-seven years of teaching experience in mechanical drafting. He was an active member of the Canadian Standards Association (CSA) Committee on Technical Drawings. Mr. Jensen has represented Canada at international (ISO) conferences on engineering drawing standards, which took place in Oslo, Norway and Paris, France. He also represented Canada on the ANSI Y14.5M Committee on Dimensioning and Tolerancing. He is the successful author of numerous texts including Engineering Drawing and Design, Fundamentals of Engineering Drawing, Geometric Dimensioning and Tolerancing for Engineering and Manufacturing Technology, Computer-Aided Engineering Drawing, and Home Planning and Design. Before he began teaching, Mr. Jensen spent several years in industrial design. He also supervised the evening courses in Oshawa and was responsible for teaching selected courses for General Motors Corporation apprentices.
