536 Intermediate/Advanced GD&T

Neumann textbookFor Whom Intended  Individuals performing inspection, design, manufacturing and assembly. Understanding geometric dimensioning and tolerancing is essential for anyone reading blue prints.

Brief Course Description  Starting where Course 535, GD&T leaves off, this course covers units 7-17 of Al Neumann's Geo Tol Pro Workbook, A Practical Guide to Geometric Tolerancing per ASME Y14.5 - 2009. This course discusses major Y14.5 2009 changes such as maximum material boundary (MMB), least material boundary (LMB), and regardless of material boundary (RMB). The instructor covers more complex GD&T situations, including datum feature modifiers, more on datum reference frames, form tolerances, orientation tolerances, profile and position tolerances in further detail. Coaxial tolerances, fixed and floating fastener formulas along with their application are discussed throughout the color workbook.

Students will participate in practical exercises to demonstrate their understanding of the material covered.

Participants successfully completing this course will be able to understand, evaluate and use intermediate and advanced geometric dimensioning techniques. They will be able to read and fully understand blueprint drawings of mechanical devices.

Diploma Programs  This course may be used as an optional course for TTi’s Metrology/Calibration Specialist (MCS) Diploma Program, or for any other TTi specialist diploma program.

Related Courses Course 535, GD&T: Practical Interpretation and Measurement, serves as an introduction to the concepts covered in more depth in this course. Day one of Course 535 is also offered separately as Course 534, Introduction to Geometric Dimensioning and Tolerancing. Additional courses on Tolerance Stacks are also planned.

Prerequisites  Students must complete TTi course 535, or be able demonstrate equivalent knowledge. This course is aimed toward individuals involved in a related technical field.

Text  Students who have already taken the prerequisite course 535 should bring their copy of Al Neumann's Geo Tol Pro Workbook, A Practical Guide to Geometric Tolerancing per ASME Y14.5 - 2009. This full-color book, which is considered the definitive reference work in the GD&T industry, may be purchased by those students who do not already have a copy.

Course Hours, Certificate and CEUs  Open courses meet seven hours per day. Upcoming presentation dates can be found on our current open course schedule. Class hours/days for on-site courses can vary from 14-35 hours over 2-5 days as requested by our clients. Upon successful course completion, each participant receives a certificate of completion and one Continuing Education Unit (CEU) for every ten class hours.
