Every product manufactured by any process is subject to variation. Tolerances are engineering specifications of the acceptable levels of variation for each geometric aspect of a part or assembly. Tolerance stack up analysis is the technique used to understand the cumulative effects of these tolerances (accumulated variation) and to ensure they are at acceptable levels for the product function. This course is designed to apply the different tolerance stack up analysis techniques on the parts as well as assemblies. The effect of GD&T on the stack up analysis and statistical tolerancing are also explained in detail in this course. The topics in this program will be explained with PPTs, relevant videos, hands-on exercises, and case studies. Highly interactive sessions are planned through instructor-led training.
