This practical workbook systematically teaches the crucial skills that manufacturing trades students need to accurately read and correctly interpret blueprints. Students master each new concept through immediate hands-on problem-solving. No prior blueprint reading knowledge is required, and no materials are required beyond a pencil and eraser. BLUEPRINT READING FOR MACHINE TRADES, 7/e begins with the absolute basics, then progresses to visualization, and finally, to multiview drawings. Diverse questions are provided to stimulate interest, including short answer, multiple choice, true/false, and sketching. The book has proven itself in both classroom and industrial settings, and has also been widely used for self-teaching. This edition reflects the latest industry standards, including ASME Y14.5-2009 and CAN3-B78.1-M83.
