GeoTol Pro Applications and Stacks Course

Course Access: 365 days access
Course Overview


This course is presented in a sports-caster style presentation with Al Neumann and Scott Neumann presenting the advanced topics of GD&T; Applications and Tolerance Stacks. 1 year access. This course does not review the basics, so make sure you have a good understanding of GD&T before going on to this advanced course. Pre-requisite is the GeoTol Pro GD&T Fundamentals Online Course.

The Applications and Tolerance Stacks workbook is recommended, but not included.

Tolerance Stacks

The stacks section is contained in the first 6 units of this program, and is designed to teach students the fundamental principles of tolerance stacks.  The student will learn a variety of stack procedures, beginning with simple linear stacks on detail parts in units 1 and 2, and migrating to linear assembly stacks in Unit 3.  Unit 4 begins with axial detail stacks, and moves on to complex axial assembly stacks in unit 5.  Orientation tolerance stacks are covered in unit 6 and melded together with axial boundary assembly stacks to provide the participant with a complete understanding of the stacks process.  Students will use this knowledge to perform tolerance stacks to ensure the design criteria is met in the application case study problems.

Design Applications

The applications section is a total of 10 units, (7 thru 17). Unit 7 begins with a quick review of the fundamentals of geometric tolerancing and a few basic applications of geometric tolerancing on simple detail parts. The following units are a series of case study examples, where the students will learn to establish datum reference frames and apply geometric tolerancing to a variety of parts.  There are a multitude of simple to complex sheet metal, cast, turned and milled parts, and welded assemblies. The case study examples start out simple, but generally grow in complexity as the units progress.  In the beginning of each unit there will be an introduction explaining the issue at hand and the necessary functional requirements to be met.  Some examples provide detailed explanation, and in other instances, examples are incomplete by intent to make the problem less complex. After the parts are toleranced to achieve functional requirements, there are tolerance analysis stacks and reallocation exercises the student must perform to ensure the parts meet the established requirements detailed in each introduction.
