📐 Tolerance Stack-Up: The Hidden Factor Behind Assembly SuccessIn mechanical and sheet metal design, every dimension has a tolerance. While each individual part may be within specification, the combined variation across multiple components can lead to unexpected assembly issues. This cumulative variation is known as Tolerance Stack-Up.Understanding and controlling tolerance stack-up helps engineers:✅ Improve assembly fit and functionality✅ Reduce rework and manufacturing costs✅ Increase first-pass yield✅ Enhance product quality and reliability✅ Build designs that are easier to manufactureAs design engineers, our responsibility goes beyond creating accurate CAD models. We must ensure our designs remain functional despite real-world manufacturing variations.
