I’m pretty sure for machining folks, there are times that you cannot find the tolerance for linear or angular dimensions in drawing or print due to it is designed that way or its a very old revision.
The answer could be by referring to ISO 2678 for the tolerance table but before that you’ll need to know what tolerance grade or surface finish the designer intended to achieve.
ISO 2768 is a set of rules and guidelines used in machining and manufacturing to ensure that the dimensions of a product or part are within acceptable limits. It’s like a set of rules that tell us how much things can be a little bit bigger or smaller than what we intend.
For example, if you’re making a metal part using a machine, ISO 2768 helps you decide how precise you need to be with measurements. If it allows for a tolerance of ±0.1 mm, it means your part can be up to 0.1 mm bigger or smaller than the exact size you want, and it’s still considered acceptable.
In machining, this standard helps ensure that parts fit together correctly and work as intended. It also guides quality control to make sure the parts meet the necessary specifications without being too strict or too lenient with the measurements.
I hope this helps, let’s get back to our daily grind. Happy Monday!
