Overview

About the Product

The 6th Canadian edition of Jensen’s Interpreting Engineering Drawings is aimed at students in mechanical apprenticeship programs, including Machinists, Tool and Die Makers, and Industrial Millwrights – who need to understand the basic – and more complex – concepts involved in technical drawings and the communication of technical information. Jensen is the only blueprint reading text on the market designed to provide customized drawing interpretation courses for each and every student. Designed to contain far more information than is normally required for any traditional program, this text provides the instructor with the opportunity of selecting units of instruction that would best suit the needs of the students in that particular area or industry. It provides the theory and practical application for individuals to develop the intellectual skills needed to communicate technical concepts used throughout the international marketplace. The first chapters cover the core concepts of blueprint reading from orthographic views to section views. The second and third sections include topics of different fields of mechanical drafting such as structural steel, welding, piping, and GDT. Jensen is the only text on the market that follows CSA standards.

Features

  • The entire text is developed around the latest drafting standards accepted throughout industry.

  • Tables are provided to summarize useful data for future reference.

  • This text covers both imperial and metric measurements. Both systems are introduced early in the text and are reinforced in both theory and practical applications through the assignments at the end of each unit.

  • Similar topics are organized into discrete units of moderate length and are followed by immediate application by way of assignments.

  • Numerous examples and illustrations are provided to show the applications of each concept described. Color is used extensively in the text to draw attention to important concepts and changes of state from one part or location to another.

About the Author

Cecil H. Jensen

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.

New to this edition

  • Standards update: All drawings in the text have been updated to conform to the latest CSA and ASME drawing standards.
  • Increased coverage of geometric tolerancing.
  • Expanded sketching practice: the use of sketching techniques as a means of better understanding and communicating technical information has been greatly expanded throughout this text. This becomes increasingly more important as computer-aided drafting continues to rapidly replace board drafting.
  • Enriched Instructor’s Manual includes the Nelson Instructor’s Guide to Classroom Engagement, providing instructors with an overview of the theory and models of active learning. As well, each chapter in the new Instructor’s Manual covers learning objectives, teaching tips to overcome barriers, some 3-D representations of projects for instructors to assist the students in visualizing the part(s) in a more realistic representation than in their traditional orthographic layouts, sample tests, and the solutions to assignments.
  • Computerized Test Bank Nelson Education Ltd. understands that a good quality multiple-choice test bank can provide the means to measure higher-level thinking skills as well as recall. Recognizing the importance of multiple-choice testing in today's classroom, we have created the Nelson Education Testing Advantage program (NETA) to ensure the value of our high quality test banks. The new NETA test bank has been enhanced with more multiple-choice questions and better formulated questions!
