In the stamping process to read drawings, when, location, marking first look at the degree of position accuracy measurements in addition to whether there are other restrictions, such as the largest entity or entities, the minimum requirements, if these two requirements, there will be in the position accuracy test is very to help. If not, place the same degree of testing is necessary to pass only the rules of the method used, find the minimum or maximum parts. Let's Take the hole in the largest state entity requires hole position accuracy requirements.

    Hole in the largest entity requires a state inspection with testing.

1. 2 base diameter of pin hole to take minimum. (For reference holes also have the greatest physical requirements)
2. Two location-degree requirements of the size of the cavity to the lower pin (for the position have the greatest degree of physical requirements) minus the bits
Degree of size of home.
3. If in a plane parallel to the surface or there are multiple locations degree requirements, as much as possible to do with the test marketing.
