Check Fixtures & Inspection Gauges

To determine if a dimensional callout on a drawing needs to be confirmed using a check fixture or inspection gauge, consider the effects to the production process if the part was made with the dimension in question out of tolerance.

• How severe would the effects be to the process if the part were out of tolerance?
• Given the manufacturing process and previous checks, how likely is this defect to occur?
• How difficult is the defect to detect or spot without using a check fixture or inspection gauge to confirm accuracy?

You may already be asking yourself these questions as part of a Failure Mode & Effect [FMEA] analysis. A check gauge is a great way to increase defect detection and ensure the process is held to the right dimensional tolerance.
