Mica product data for AI layer and cut-part review
The Census manual places mica products within miscellaneous nonmetallic mineral manufacturing.
NAICS 327999 · All Other Miscellaneous Nonmetallic Mineral Product Manufacturing
The Census manual places mica products within miscellaneous nonmetallic mineral manufacturing. A specific cut-part exercise gives this broad category a concrete contributor task, with all dimensions and assembly rules invented for the pilot. Census mica-product scope
Make paper props representing layered mica parts, an original cutting drawing and fictional material tickets. Give two variants the same outline but different layer references. Ask an assistant which source ticket supports each part and which stacked view leaves the layer count unresolved. Include a corrected drawing that moves one hole without changing the part-family name.
Annotate parent sheet, layer reference, part revision, hole position and evidence view. Hold out an unfamiliar outline during evaluation. Score wrong-layer matches, use of the old drawing and unsupported observations about hidden layers independently. The reference key should describe the supplied evidence without assigning dielectric, thermal or mechanical performance to a photographed part.
Use ordinary paper and neutral identifiers. Real customer electrical designs, proprietary laminating recipes and outside laboratory reports need authority and qualified review. Explain the part-association task and checked examples to prospective buyers. Their accepted brief should determine the data depth and permitted source material required before further preparation for licensing.

Original Fiund exercise
A split line visible only from the edge
Colored paper layers stand in for an invented sheet mineral part. One photograph is face-on and another side-on.
| Record | Source | What it records |
|---|---|---|
| 1 | Layer diagram | Part M8 layers counted from blue face; join between layers 2 and 3. |
| 2 | Side view | Blue face visible, opening at boundary 2/3. |
| 3 | Face view | Top surface intact; internal boundary not visible. |
Question for the model
What should the label say about the opening?
Show the reference answer and checks
Record an opening at boundary 2/3 from the blue face, supported by records 1 and 2. Record 3 describes an intact visible top surface and cannot disprove an internal observation. Keep separate view coverage and avoid assigning material cause or function.
- Treating an intact top face as proof all layers are intact
- Counting from the unlabeled face
Fields to preserve
- layer_origin
- Fixes boundary numbering
- boundary_pair
- Locates the observed separation
- view_type
- Limits what face and edge views support
Test another case
Reverse the side view but retain the blue marker; require the same boundary annotation.
No actual mica grades, electrical specifications, cutting methods or material qualification.
Discuss a contribution
Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
