When a part does not have a print provided, we expect our partners to inspect the part to the CAD file and document the following specifications to verify correct setup and programming:
- Correct material used
- Material test reports if required
- Plating and certification
- Overall length
- Overall width
- Overall height
- All hole locations, diameters and depths
- Thread sizes and depths (note: thread depths are a frequent failure)
- Threaded holes square to the surface (note: hole perpendicularity is a frequent failure)
- Pocket/step depths (at least 1 depth per face)
- Corner radii correct to model (note: this is a frequent failure)
- Each face should have at least 1 feature check for X and Y location from zero edge
- Surface roughness (125 or better unless noted)
- All inserts are installed correctly
- All parts are deburred
- All parts are clean and threaded holes do not have chips packed in the bottom
Note: All changes made to inspection documents must have approval traceability. It is not acceptable to alter, obliterate, or otherwise cover over documented results. The usage of whiteout is not permitted. The presence of these conditions is a non-conformance. If an error is made, the error should be struck through with one line (leaving the original data discernible) and should be initialed by the person making the change.
