MCH 220 - Geometric Dimensioning and Tolerancing

Credit(s): 3

Prerequisite(s): DDSN 135 or MCH 122, MCH 129.
This course provides the basics of how to apply GD&T in metrology and CAD, including knowledge of the symbols, hands-on measurement of parts, and the use of CMMs. Students will learn the types and causes of measurement error and perform measurement setups. They will also learn about flatness, straightness, circularity, parallelism, angularity, concentricity, total run outs, position tolerancing, and gauge design for both soft and hard gauges. (Fall Semester)

Course Learning Outcomes: Upon completion of the course, students will be able to

Identify and use the common GD & T industry symbols.
Understand and use fixturing for checking parts.
Understand and use common gauges for checking parts.
Identify and use different types of gauging methods in industry.
Identify proper Datum usage.
Use precision measuring tools to check GD & T Use a CMM to check GD & T.
