Learn how to take the guesswork out of the manufacturing process, to improve quality and avoid costly mistakes.

After taking the introductory GD&T course, students will grasp the fundamentals of GD&T, such as datums, position with Maximum Material Condition (MMC) and Regardless of Feature Size (RFS) modifiers, parallelism, profile etc. However, they may still lack the intimate knowledge of how to apply geometric tolerancing expertly and perform tolerance stacks to define and optimize their product design. 

This Applications and Tolerance Stacks course teaches one how to take GD&T skills to the next level and apply and perform tolerance stacks using a series of case study problems including sheet metal, machinings, plastic parts, castings etc. Being able to identify a tolerance on a part can influence the product’s cost and performance. Learning the skills in this course will help the learner balance functionality with manufacturing capabilities.

The case studies in this course require students to establish datum reference frames and apply geometric tolerancing based on defined functional requirements. Afterwards, they must perform tolerance stacks to ensure design requirements are met. This process links the concept that the proper selection of the datums, as well as position and profile values on individual parts, have a great effect on the accumulation in the overall assembly. The exercises are interactive and discussed in student groups and as a class to support an engaging class environment.

By participating in this course, you will learn how to successfully:

  • Employ the proper application of geometric tolerancing on parts and assemblies.
  • Perform linear and axial tolerance stacks. 
  • Reallocate tolerances to meet manufacturing capabilities.

Special Requirements:
Students should bring calculators to class. Participants may bring drawings to class for discussion.

Who Should Attend?
Engineers, designers and drafters, as well as quality, tooling and manufacturing personnel. As a prerequisite, it is recommended the students attend the Geometric Tolerancing Fundamentals class or have a strong understanding in geometric tolerancing fundamentals.
