Tolerance design

Hae viimeistään 25.8.2019

This course is organised in Finnish.

The course consists of the following topics:

  • Benefits of tolerance design
  • Consideration of product level requirements in tolerance design
  • Consideration of the manufacturing process variation in tolerance design
  • Utilization of measurement data of components in tolerance design
  • Determination of a tolerance chain and calculus of its total variation

Course provides basic skills for a desing engineer to take the dimensional variation of produced mechanical components into account in daily design work.

This course is organised in Finnish.

After completing the course, the student understands the significance of tolerance design as an essential part of the product development process and can independently apply it as a basic tool in daily design work. The student understands the variation in the manufacturing, measurement and assembly of components of the product and can take the variation into account in the dimensioning of parts and in setting realistic tolerances for them.

In addition, the student is able to convert critical product functions to critical dimensions, and to determine tolerance chains affecting them and to calculate total cumulative variations in these chains. The student is able to evaluate product structures in their variation sensitivity point of view and is able to optimise product structures so that dimensional variation of components has minimal effect to the product quality. The student understands the importance of locator elements between components and their key role in component dimensioning and in tolerance chain determination.
