Tolerance Stack Ups for Mechanical engineers with Six-Sigma

Stack up and Tolerance Design is all about quality, or in other words, the allowable parts to be rejected during the process. In escence, this results in an iterative process between the design department, manufacturing and the customer. In this course you will learn the concepts to master plus/minus tolerance stack ups in 2D.

At then end, you will become a valuable member for your company because you will be capable to assess assemblies and propose changes to meet critical requirements. Although currently there are several software which run complex tolerance analysis in 3D, in my experience, most of the times you can simplify the problem with a 2D analysis, so as mechanical designer YOU MUST be capable of performing 2D analysis in order to save valuable resources to the company. First, you will learn the basics: The definition of nominal value, tolerance, standard deviation, normal distribution and the importance of tolerance analysis in mechanical design.

Then. you will learn how to create the sketch (loop) to follow in the calculation of tolerance analysis. Several exercises will be provided so you can practice this process.

Next you will Learn how to perform a linear stack ups with three approaches: Worst Case: When no rejections are allowed. This apporach results in the most expensive, but it is used in critical applications. Statistical: Some rejections are allowed.
