Acclimating Mechanical Designers to Manufacturing Tolerances in the Freshman Year It is often a challenge for beginning mechanical designers to conceptualize and judgeappropriate specification of dimensional tolerances of parts. The Mechanical EngineeringTechnology Program at [University Name] applies a hands-on approach which acclimatesstudents to tolerancing issues through a freshmen course sequence involving manufacturingprocesses, CNC, and mechanical detailing. Students learn to perform machining and formingprocesses to expected tolerance specifications—and to inspect their work. Toleranced part printsand inspection sheets reinforce expectations and provide examples of standard practice. Springsemester experiences in the CNC lab allow students to focus on sources of variation whenoperator error is negligible. The entire sequence culminates with design teams designing anassembly prototype which must be manufactured to their specifications by another team. The early awareness and experiences encountered by these students their freshmen yearprovide a foundation for future courses and design projects.
