Title: Interpret geometric dimensioning and tolerancing (GD&T) from orthographic prints.
Course: Precision Machining Technology III (13203-III) > Section: Using Engineering Drawings and Sketches for CNC Machining

Interpretation should include

- features with and without size
- tolerance zones (e.g., basic dimensions)
- geometric tolerancing categories
- geometric tolerancing characteristics and symbols
- symbols associated with feature control frames
- maximum and minimum material condition (e.g., calculating actual position)
- datums.

Teacher Resources:

- Autodesk
- FS Wizard
- NC Viewer (CNC simulation)
- Phillips Machinist, Phillips Corporation
- Vericut

Process/Skill Questions:

- What are some geometric symbols associated with orthographic prints?
- What is the difference between geometric tolerances and standard tolerances?
- What is the importance of a datum?
- How would you describe maximum material condition (MMC), least material condition (LMC), and regardless of feature size (RFS)?
