What is tolerance analysis?
Tolerance analysis is the process that analyzes dimensional variations in mechanical parts and assemblies based on predefined tolerances. The results enable designers to ensure assembly fit without spending too much time and money on machining.
Why is tolerance analysis important for design to manufacturing?
Components must be designed within specific dimensions–or manufacturing tolerances–so that when they are manufactured, they fit well together. Tolerance analysis before producing a component helps designers save cost and time by avoiding excessive machining operations for tighter tolerances.

Frequently asked questions (FAQs) for tolerance analysis in manufacturing
-
How can the Product Design & Manufacturing Collection help with the design-to-manufacturing process? As a CAD-embedded tolerance stackup analysis solution, Inventor Tolerance Analysis software helps streamline the entire design-to-manufacturing process. It supports worst-case, general statistical, and Root Sum of Squares (RSS) analysis methods. This software automates tolerance stack-up tasks that are typically handled by spreadsheets, including calculating the effects of geometric tolerances, clearances around fasteners and pins, statistical results, and managing product requirements.
-
How will the Product Design & Manufacturing Collection save time when performing a tolerance analysis? With Inventor Tolerance Analysis software in the Product Design & Manufacturing Collection, stackups automatically capture the relationships defined in the assembly model. If you use model-based definition capabilities, you can edit tolerance values directly inside the program, further streamlining the process between design and manufacturing.
-
What tolerance stack-up features are available with the collection? Inventor Tolerance Analysis software includes multiple features to streamline the design-to-manufacturing process. Reduce tolerance issues during manufacturing by running an analysis of the geometric dimensioning and tolerancing (GD&T) in a 3D model. Calculate the worst-case, RSS, and statistical results of the analysis, and report metrics for statistical results as Cpk, Sigma, DPMO, or Yield. You can also generate reports to communicate analysis results and cost-control efforts to manufacturing and quality engineers.
