Course Description
Tolerance stack analysis is actually the study of the mutual relationship between the allowed deviation limits between parts and assemblies. Stack computation improves understanding of the design solution, allows early identification of problems starting while still in the design stage, forms the basis for decision making and is used to optimize tolerances to reduce costs and enhance benefit.
The course provides the theoretical knowledge and practical know-how to perform stack computation and includes heavy practical exercises of generic problems, exercises, and full solutions of real problems (the possibility of applying exercises to parts and assemblies of your company is contingent on previous submission of drawings and assemblies). This is an advanced GD&T course.
