In modern industrial environments where responsibility for quality control is being placed upon individual workers, the understanding of dimensional metrology principles is becoming increasingly important. That's why the fourth edition of our best-selling Fundamentals of Dimensional Metrology book offers a direct path to understanding and applying the principles, techniques, and devices used within the dimensional metrology field today. This edition uses both the Metric and Imperial systems, yet emphasizes Metric measurement devices and concepts in all examples for greater consistency with the latest industry trends. Information on particular devices and concepts, previously presented in separate chapters, has been combined to improve the logical flow of the material. New chapter-end review questions have also been added to eliminate the potential for ambiguity, allowing readers to gauge their understanding as they progress through the book.
