# TDSN 125 - Geometric Dimensioning & Tolerancing

2 Credit: (1 lecture, 1 lab, 0 clinical) 2 Contact Hours: [TDSN 105 ]

This technical course is structured around a workbook approach to learning. The principles of geometric dimensioning and tolerancing are applied to reading blueprints and engineering drawings. The most current industrial standards are referenced. Topics of study include the following geometric tolerances: form, profile, location, orientation, and runout. The specific tolerances covered are concentricity, circularity, straightness, parallelism, flatness, cylindricity, position, perpendicularity, angularity, circular runout, total runout, profile of a surface, profile of a line, and symmetry. Other areas of study are datums, datum targets, the interpretation of fits, limits and tolerances, and tolerancing for the location of features.
OFFERED: spring semesters

Course Goals/ Objectives/ Competencies:
Goal 1:  Explain the basic concepts of geometric dimensioning and tolerancing (GD& T).

1. Define geometric tolerance terms.
2. Understand and interpret feature control frame information.
3. Interpret traditionally dimensioned drawings and recognize where to apply GD& T concepts.
4. Read blueprints that contain GD& T information.
5. Analyze blueprints containing GD& T to identify the reasoning behind the GD& T application.
6. Analyze the value of incorporating GD& T concepts with traditional dimensioning practices.
7. Explain the 16 fundamental dimensioning rules.

Goal 2:  Demonstrate the application of GD& T.

1. Demonstrate the use all 12 GD& T characteristics.
2. Apply the bonus tolerance concept.
3. Utilize the Datum System for inspection setup.
