GD&T Fundamentals Based on ASME Y14.5-2009

Course code: PD02550090

The course contains 29 lessons that explain the terms, symbols, modifiers, rules, and basic concepts of geometric tolerancing as prescribed in the ASME Y14.5-2009 standard. It takes approximately 24-28 hours to complete.

Objectives

Upon completion of this course, you will be able to:

• Explain the importance of standards on engineering drawings
• Describe the types of dimensions, tolerances, and notes
• Explain why geometric tolerancing is superior to coordinate tolerancing
• Interpret the general dimensioning symbols
• Define the key terms used in GD&T
• Recognize the symbols and modifiers used in GD&T
• Explain the rules used in GD&T
• Describe the concepts of worst-case boundary, virtual condition, and bonus tolerance
• Interpret the various types of tolerance (flatness, circularity, cylindricity, straightness, perpendicularity, parallelism, angularity, position, runout, and profile)
• Describe the datum system
• Interpret applications of datum targets, size datum features (RMB), and size datum features (MMB)
