Mechanical rubber product data for AI seal and dimension checks

NAICS 326291 · Rubber Product Manufacturing for Mechanical Use
ARPM publishes rubber-product industry resources. A manufacturer can propose an original static exercise around seal identity, measurement location and the product drawing that defines the requested comparison. Association for Rubber Products Manufacturers
Draw fictional ring-shaped seals with different inner diameters and cross-sections. Use paper props, a scale reference and a mock inspection sheet. Ask the assistant to identify which measurements answer the order. Include a similarly sized ring with the wrong cross-section and a report missing the material-variant reference. The key should separate geometric evidence from the unresolved material identity.
Annotate part, material variant, measurement points, unit, specimen and drawing revision. Hold out an unfamiliar profile and table layout for evaluation. Score comparing the wrong dimension, matching by overall size alone and inventing a material association independently. A complete case should support a match without inferring compatibility or sealing performance from appearance.
Use original designs and invented readings. Actual customer applications, licensed specifications, proprietary compounds and laboratory reports need permission and qualified review. Describe the geometry-and-evidence task and checked examples in the contributor proposal. Confirm the buyer's accepted material before preparing a larger operating archive or commissioning capture.

Original Fiund exercise
Inner diameter and cross-section are not interchangeable
The exercise uses drawn rings and fictional caliper readings. It makes no fit or suitability recommendation.
| Record | Source | What it records |
|---|---|---|
| 1 | Drawing | Part K2 mock keys: inner diameter 20 mm, section diameter 3 mm. |
| 2 | Sample A | Inner 20 mm, section 4 mm. |
| 3 | Sample B | Outer 20 mm, section 3 mm; inner reading omitted. |
Question for the model
Which sample has the two explicitly documented dimensions?
Show the reference answer and checks
Neither. A matches K2's inner dimension but disagrees on section size. B matches the section size but gives an outer diameter, not the requested inner reading. The visible number 20 appears on different dimensions, so B cannot be accepted on a simple number match.
- Equating outer and inner diameter
- Ignoring section diameter after an inner match
Fields to preserve
- dimension_type
- Names the geometry each number measures
- section_diameter
- Tracks the cross-section independently
- observed_unit
- Keeps readings on a stated scale
Test another case
Supply a noncircular cross-section with a single width measurement; require a second axis or documented convention before comparing.
No actual equipment tolerances, safety-critical seal selection, customer specifications or product claims.
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.
