Traditional manufacturing classes cover engineering materials and manufacturing processes. Upon familiar with basic hand tools like calipers, micrometers, or indicators in laboratory exercises, students would understand metrology as dimension with tolerance and miss other important aspects of metrology such as shape, surface finish, and how the part shape would affect dimensional tolerances. The limited metrology knowledge would later show in capstone projects for undergraduate students and research projects for graduate students when designing and fabricating their engineering components. The issues follow when students joining manufacturing workforce in industry or research institution upon graduation.With approval from External Advisory Committee and support from industry, the Engineering Technology & Industrial Distribution department at Texas A&M University established a well-equipped metrology laboratory and integrated laboratory exercises with manufacturing curricula. Students in lower-level classes learn theory and have hands-on practice with both contact-type measuring devices and noncontact-type measuring systems before attending other manufacturing laboratory sessions. The upper-level class covers theory of Geometric Dimensioning & Tolerancing (GD&T) and introduces flipped-laboratory practice on this topic. Upon presented several metrology problems, students work in a small group to select suitable instrument, fixture for a problem. A group then takes turn to present the procedure, solution, and measured results to other groups. Preliminary test results show improvement of student understanding of GD&T after flipped-laboratory approach is implemented.
