MTTC 227 - Geometric Dimensioning and Tolerancing
PREREQUISITES: MTTC 106 - Print Interpretation or Advisor Approval.
PROGRAM: Machine Tool Technology
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019
Introduces the fundamental principles of geometric dimensioning and tolerancing according to historical current ASME Y14.5M standards. Students will interpret, measure, and apply all geometric dimensioning and tolerancing symbols and principles to industry standard technical drawings. Students will develop the ability to relate drawing requirements to actual part function and inspect parts using Geometric Dimensioning and Tolerancing standards.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Identify Geometric Dimensioning and Tolerancing symbols on drawings. (b)
- Interpret tolerances per ASME standards. (b)
- Define a datum reference frame.
- Perform inspections on parts using industry standard metrology techniques to verify conformance. (b,c)
- Use Coordinate Measuring Machines to inspect parts designed with GD and T (b,c).
- Set up parts to machine features using a datum reference frame. (a,b,c,i)
- Describe the difference between conventional tolerancing and GD and T. (b)
Note: Letters following objective correspond to ATMAE Outcomes.

- Geometric dimensioning standards
- Tolerances of form, orientation, and location
- Zones of tolerance
- Datum Reference Frames
- Calculating bonus tolerances
