Module Aims

• An introduction to design rules, and communications.
• Focusing on design drawing, dimensioning, and tolerancing standards, Datum systems, Geometrical Dimensioning and Tolerancing including: background, standards, feature control frames, geometric characteristics, symbols for boundaries and material conditions, GD&T concepts in details, review of GD&T on sample drawings, Measurement requirement understanding for parts with GD&T information, Tolerancing of flexible parts, Tolerance chain, Practical measurement of parts with GD&T information.

By engaging successfully with this module a student will:

• Understand relevant dimensioning and tolerancing standards with focus on ISO SPG standards.
• Understand the main and critical GD&T controls, rules, and modifying symbols.
• Understand datum reference frames.
• Be familiar with the impact of dimensional variation and tolerance stack-up.
• Interpret, and base engineering decisions on, part and assembly specifications.
• Conduct tolerance stack-up analysis on simple models.
