Public GDT and Tolerance Stack-Up Analysis Workshops

Online, October 14, 2011 (Newswire.com) - Geometric Dimensioning and Tolerancing (per ASME Y14.5-2009 and 1994 and the differences between them)
December 5-7, 2011

An introductory, but comprehensive, applications-based training program for all technical personnel who interpret and apply geometric dimensioning and tolerancing. This course covers GD&T principles, rules and applications, as well as the new Y14,5-2009 symbology. Participants will gain a comprehensive knowledge of GD&T techniques but also, through the use of lectures, discussion, case histories and application problems, the ability to apply these techniques to their product line.

This course shows how to interpret design drawings and CAD representation of product definitions that use the ASME Y14.5-2009 and 1994 standards. It also explains step-by-step procedures to apply the Y14.5 practices and allow dimensioning and tolerancing professionals to express their design requirements more clearly. This course allows participants the opportunity to learn and apply techniques in datum selection and tolerancing optimization. It introduces techniques in calculating more producible tolerances, choosing practical datum structures and then shows how to measure each requirement. Do's and don'ts of proper tolerancing are taught and reinforced by showing how they apply to realistic assembly tolerancing conditions.

Tolerance Stack-Up Analysis. December 7-9, 2011

Participants will be trained to apply tolerance stack-up analysis techniques, from the very simple to more complex situations. Both plus and minus and geometrically toleranced assemblies will be examined and stack-up analysis taught and practiced on each. Some concepts taught: loop analysis, number charting, virtual condition, resultant condition, inner/outer boundaries, minimum airspace, maximum wall thickness, maximum interference, minimum and maximum overall dimensions, fixed and floating fastener assembly conditions, projected tolerance zones, the logic of stack-up analysis, statistical tolerancing, etc.

Participants will be able to: Calculate minimum and maximum wall thickness, airspaces and interferences for assemblies; Create loop analysis/circuit diagrams for tolerance stack-up analysis for both plus and minus toleranced dimensions and geometric tolerances; Create both simple and complex number charts for stack-up analysis using a variety of geometric tolerances, basic dimensions, resultant conditions, virtual conditions and plus and minus toleranced dimensions; Do tolerance stack-up analysis for floating fastener situations for clearance holes, screws and shafts; Do tolerance stack-up analysis for fixed fastener situations; Calculate minimum and maximum gaps for assemblies that use a variety of datum structures; Learn a system of logic and mathematics to analyze tolerances; Calculate the effects of angular stack-up using trigonometry and proportions; Calculate statistical tolerance using a variety of methods and learn how to re-integrate these tolerances back into the assembly's details.
