Tolerance Stackup Training and Tolerance Analysis Training based on ASME Y14.5M-1994, ASME Y14.5-2009 – ASME Tolerance Analysis Training

Tolerance Stackup Training and Tolerance Analysis Training based on ISO 1101, ISO 5459, ISO 8015, etc. – ISO Tolerance Analysis Training

Worldwide Leaders in Tolerance Analysis and Tolerance Stackup Training

We are the worldwide leaders in Tolerance Analysis training and Tolerance Stackup training. Our Tolerance Stackup Training and our Tolerance Analysis training is based on the Advanced Dimensional Management method, as presented in our books “Mechanical Tolerance Stackup and Analysis,” now in its 2nd edition, and “Tolerance Stackup, Tolerance Analysis and Tolerancing Manual: Plus and Minus Edition,” which is for companies that have not yet adopted GD&T. We teach companies of all sizes how to perform tolerance analysis, how to incorporate tolerance analysis into their workflow, how to incorporate tolerance analysis into their supply chain, and how to use these techniques to achieve their quality goals. In fact, many of our customers are some of the world’s top corporations. Our Tolerance Analysis training and Tolerance Analysis software help them to consistently provide higher quality products with the lower cost. We can do the same for you. We teach our Tolerance Analysis training courses regularly around the US and around the world. Our Tolerance Stackup and Tolerance Analysis methods very powerful and they are easy-to-learn and easy-to-use.

Tolerance Analysis Training Courses and Tolerance Stackup Training Courses

When we teach Tolerance Analysis in our Tolerance Analysis Courses and Tolerance Analysis Seminars, we teach it from the point-of-view of careful application of dimensions and tolerances, looking at ways to reduce the accumulation of tolerances and how to mitigate their effects on the desired outcome. Our goal is to help you and your staff avoid problems during the design stage by employing Advanced Dimensional Management’s tolerance analysis techniques. If you need to troubleshoot and find solutions to existing problems, we also help you to understand the problem and to obtain the best solution possible.

Our goal is your success.

Onsite Tolerance Analysis Training Courses

Most of our customers have us present our Tolerance Analysis Training Courses onsite at their facility. We offer traditional Plus and Minus-only Tolerance Analysis Courses and Tolerance Analysis Seminars, we offer a combination of GD&T and Plus and Minus Tolerance Analysis Courses and Tolerance Analysis Seminars, and we offer GD&T-based Tolerance Analysis Courses and Tolerance Analysis Seminars. Course content can be suited to your needs and practices.

Along with teaching your staff how to perform Tolerance Analysis and Tolerance Stackups, we want to help them to understand the differences between different Dimensioning and Tolerancing and GD&T schemes. Tolerance Stackups are done using different Dimensioning and Tolerancing and GD&T schemes on sample assemblies, helping the student to understand the implications of the Dimensions, Tolerances and GD&T. Tolerance Stackup and Tolerance Analysis are an integral part of Functional Dimensioning and Tolerancing – in fact, the only way to know if a Dimensioning and Tolerancing Scheme is functional is to do a Tolerance Stackup.

Basic Tolerancing, Level 1 and Level 2 Tolerance Analysis and Tolerance Stackup Courses are available, both in our standard format or customized to your products. Custom Courses can be anything you want. Our training has been successful in a variety of environments and contexts.

Tolerance Analysis Books and Tolerance Analysis Reference Materials

Our techniques are presented in Bryan’s very popular book “Mechanical Tolerance Stackup and Analysis”, 2011, CRC Press, now in its second edition. The Advanced Dimensional Management method is easy to learn, easy to use, applies to virtually any geometry, and works with ASME GD&T and ISO GD&T. We offer a Plus-and-Minus-only tolerance analysis book “Tolerance Stackup, Tolerance Analysis and Tolerancing Manual: Plus and Minus Edition,” which is for companies that have not yet adopted GD&T. We also offer workbooks for GD&T and Plus and Minus, the “Workbook for Mechanical Tolerance Stackup and Analysis: GD&T and “+/-” and the “Workbook for Tolerance Stackup, Tolerance Analysis and Tolerancing Manual: Plus and Minus Edition.” Contact us today to find out how we can help you and your company learn, improve, and implement tolerance analysis techniques.

Worst-case, statistical and adjusted statistical tolerance analysis methods are presented. Many examples and exercises are solved using both techniques, allowing the student to compare the results and gain a better understanding of their pros and cons. For most of our students, the light bulb comes on during our tolerance analysis, as this is where they gain a true understanding of GD&T, when they can see how it converts into numbers in a tolerance analysis solution. Tolerance analysis is actually variation analysis, a study and quantification of the potential effects of accumulated variation in as-produced parts and assemblies.

Advanced Dimensional Management’s Tolerance Stackup Software Toolset

Our Courses stress the importance of a standardized approach to solving Tolerance Stackup problems and the importance of a standardized tool for reporting the results. Students learn to use our Tolerance Stackup Report Form and to create Tolerance Stackup Sketches, both of which are critical elements to solving Tolerance Stackups and reporting the results. These forms are part of Advanced Dimensional Management’s Tolerance Stackup Software Toolset.

We suggest you consider our GD&T and tolerance analysis training courses to help you understand your variation, how to quantify it, how to mitigate its effects in your products, and how to implement dimensional management throughout your enterprise.


Bryan R. Fischer is President of Advanced Dimensional Management LLC in Sherwood, Oregon, offering leading-edge training and consulting in Dimensioning and Tolerancing, GD&T, Tolerance Stackup and Analysis, Dimensional Management, Design, Standards and Quality.

Bryan and our other trainers are ASME Certified Senior Level GD&T Professionals. Bryan and others are members of several ASME sub-committees. Bryan a member of the ASME Y14.5 Sub-committee Support Group, the US TAG to ISO TC213 which develops ISO GPS (GD&T, etc. standards, and directly involved in developing the ASME Y14.5 standard and ISO 1101 and 5459 standards. He is recognized as a leading authority in the theory and application of Dimensioning and Tolerancing, GD&T, Tolerance Analysis and Stackups and Dimensional Management.

He is a published author, having written several books on Geometric Dimensioning and Tolerancing, Tolerance Stackups and Tolerance Analysis. His books “The Journeyman’s Guide to Geometric Dimensioning and Tolerancing: GD&T for the New Millennium” now in its 12th revision, the GD&T Update Guide: ASME Y14.5-2009: Changes, Improvements, and Clarifications, and the GD&T Visual Glossary will be used as the basis for the seminar. His book “Mechanical Tolerance Stackup and Analysis,” now in its second edition (CRC Press 2011) is the preeminent title on Tolerance Stackups and Tolerance Analysis available.

In 2008 Bryan revised the 11th Edition of The IHS Global Drawing Requirements Manual (the DRM), and wrote an extensive new chapter on using Digital Data as Design Deliverables and Annotating Solid Models. This is a book in itself, and is based on the ASME Y14.41-2003 and ISO 16792-2006 standards, and includes material not found in either of those standards. We are leaders in 3D Model-Based Product Definition (3D MBD) and 3D Model-Based Enterprise (3D MBE) Implementation techniques training and consulting. Check out our Books and Materials section and our 3D PMI, MBD, and Advanced Applications of Solid Modeling Seminar and other 3D MBD and 3D MBE courses for more information.
