TOLERANCE ANALYSIS RESOURCES

What is Tolerance Analysis? Why is It Needed? How to Do It?

An introduction to the what, why, and how of tolerance analysis for manufactured products based on mechanisms. Topics covered include:

  • What is tolerance analysis and why is it needed?
  • What products need tolerance analysis?
  • How to do tolerance analysis?
  • What is functional tolerance analysis?
  • What are the benefits?

When to Use 1D, 2D, and 3D Tolerance Analysis?

Learn about 1D, 2D, and 3D stack-up modeling and analysis options, their differences, when to use them, and their tradeoffs for tolerance analysis. Here’s the contents:

  • What is 1D stack-up tolerance analysis?
  • What is 2D stack-up tolerance analysis?
  • What is 3D stack-up tolerance analysis?

What are Worst Case, RSS, and Monte Carlo Stackup Calculation Methods?

Which method(s) to use depends on factors such as how critical a stackup is, how many components, or the complexity of geometries. This article overviews:

  • Worst-case stack-up calculations
  • Statistical stack-up calculations
  • RSS stack-up calculations
  • Monte Carlo simulation stack-up calculations
  • Additional stack-up calculation methods

What is Tolerancing in the Manufacturing Industry?

Measuring a part to ensure if it is within tolerances.

Overviews tolerancing in the manufacturing of mechanical products, Topics:

  • Brief history of tolerancing
  • How are tolerances measured?
  • How are tolerances specified?
