Mechanical Tolerance Stackup and Analysis

Written by one of the foremost authorities in the field, this newly revised reference presents the necessary background and proven step-by-step procedures for solving both simple and complex tolerance analysis problems. Using the techniques described in this text, design engineers can ensure that parts and assemblies will satisfy their intended functions. In addition, manufacturing, inspection, assembly, and service personnel can use the methods discussed to troubleshoot designs, verify in-process steps will meet objectives, and find ways to improve performance and reduce costs. This new edition includes many updates and improvements to provide a clearer, easy-to-understand, comprehensive volume.

Use Tolerance Analysis Techniques to Avoid Design, Quality, and Manufacturing Problems Before They Happen

Often overlooked and misunderstood, tolerance analysis is a critical part of improving products and their design processes. Because all manufactured products are subject to variation, it is crucial that designers predict and understand how these changes can affect form, fit, and function of parts and assemblies—and then communicate their findings effectively.

Written by one of the developers of ASME Y14.5 and other geometric dimension and tolerancing (GD&T) standards, Mechanical Tolerance Stackup and Analysis, Second Edition offers an overview of techniques used to assess and convey the cumulative effects of variation on the geometric relationship between part and assembly features. The book focuses on some key components: it explains often misunderstood sources of variation and how they contribute to this deviation in assembled products, as well as how to model that variation in a useful manner.

The book includes step-by-step procedures for solving tolerance analysis problems on products defined with traditional plus/minus tolerancing and GD&T. This helps readers understand potential variations, set up the problem, achieve the desired solution, and clearly communicate the results.

With added application examples and features, this comprehensive volume will help design engineers enhance product development and safety, ensuring that parts and assemblies carry out their intended functions. It will also help manufacturing, inspection, assembly, and service personnel troubleshoot designs, verify that in-process steps meet objectives, and find ways to improve performance and reduce costs.
