Tolerances determine how parts interact.
By mastering standards like ISO 2768 and ISO 286, engineers can walk the fine line between a part that is "good enough" and a part that is "perfectly expensive." In manufacturing, that distinction is where profits are made. tolerance standard
There is a direct correlation between tight tolerances and manufacturing cost. Tolerances determine how parts interact
Not every dimension on a drawing needs a specific tolerance attached to it. That would make the drawing unreadable. ISO 2768 sets "General Tolerances" based on the size of the part. tolerance standard
