Tolerance Stack-Up

Tolerance stack-up refers to the cumulative effect of individual part tolerances in an assembly, considering how variations in size, shape, or position can affect overall fit and function. Imagine building a piece of furniture: each component has specific measurements, but slight differences in those dimensions can lead to a final product that's not quite right. Stack-up analysis helps engineers predict potential issues, ensuring that parts will work together properly and meet design specifications. By understanding these tolerances, manufacturers can improve quality and reduce costs, leading to better-performing products.
