Critical Concepts of Tolerance Stacks ASME Y14.5 -1994 & 2009 Advanced Level
This 3-day advanced-level course provides an in-depth explanation of how to use tolerance stacks to analyze product designs and how to use geometric tolerances in stacks. The course can be conducted in three eight-hour sessions or with flexible scheduling, including five mornings or five afternoons.
You’ll learn the essential methods and concepts used for creating 1D part and assembly tolerance stacks. The course discusses how virtual condition affects part assembly, stack methods, and using the stack form and spreadsheet. You’ll practice calculating part and assembly stacks using coordinate dimensions, runout/concentricity, equal bilateral/unilateral profile, multiple geometric tolerances, position tolerances (RFS & MMC) with datum references at MMB, and using form and orientation applied to features and features of size.
Each participant receives:- Critical Concepts of Tolerance Stacks Course Book
- Critical Concepts of Tolerance Stacks Exercise Workbook
- Tolerance Stacks Drawing Package
- Tolerance stack Excel spreadsheet template
- Tolerance Stacks Summary Chart
- Y14.5-1982 / 1994 / 2009 Effects on Tolerance Analysis Comparison Chart
The course features all the topics covered in the 2-day foundational level course, including numerous practice problems and in-depth coverage of tolerance stacks applications based on the ASME Y14.5 1994 and 2009 Standards. However, this advanced-level class provides even more tolerance stacks practice with fifteen additional stack-up exercises.
