The manufacturing process is never 100 percent perfect. No matter how hard manufacturers try, there will still be variations from the original design and specifications due to machine inconsistencies or even human error. This can be a problem even if the variations cover only a few millimeters or less; in parts that require precision and accuracy, the smallest inconsistencies can render them useless.
It’s important for designers and engineers to take this percentage of imperfection into account. The most common way to do this is through a process called “tolerancing”. By using tolerancing, designers and engineers can state the allowable variations for their products or components in their drawings or 3D models. These, in turn, allow manufacturers to create an item that functions as desired — even if its specifications don’t exactly match the “as intended” dimensions to the last millimeter or decimal point.
Tolerancing can be applied using several different standards, and one of the most common is the set of standards from the International Organization for Standardization. ISO tolerance is used in many projects and by numerous companies because it results in reasonable variations while still maintaining the integrity and fit of the original design.
You can learn tolerancing on your own but, if you don’t have the time for it, you can always get the help of ISO tolerance freelancers from Cad Crowd.
