Tolerance stackup analysis is a method used to predict the cumulative effects of tolerances on the overall performance and functionality of a product or system.
By performing tolerance stackup analysis early in the design process, companies can avoid costly rework, reduce production errors, and improve overall product quality.
In manufacturing, tolerance refers to the permissible variation in a component or assembly’s size, shape, and position. Tolerance stackup analysis evaluates the potential impact of the accumulation of these variations on the product’s overall performance.
The goal of tolerance stackup analysis is to ensure that the product or system will function properly within the specified tolerances. The process involves modeling the product or system in a computer-aided design (CAD) software and simulating the effects of tolerance variations on the dimensions and characteristics of the components.
Tolerance stackup analysis can be used in a wide range of industries, including automotive, aerospace, and consumer goods. It helps to identify critical dimensions and tolerances that require tighter control to ensure the product or system will perform as intended.
