Compatibility Between the Product Geometry and Process Route
The review separates the intended operation from product-family assumptions and drawing-specific constraints.
| Review area | Assigned technical basis |
|---|---|
| Process purpose | Glass Edge Grinding: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |

|---|---|
| Geometry and available forms | Positive/negative meniscus, bi-convex/concave, plano-convex/concave and asphere |
| Dimensions and thickness | 10 to 90 mm cited HT/HTultra lenses; custom aspheres up to 200 mm diameter |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Centered ground edge, bevel or protective chamfer |
| Inspection | Interferometry, centration, focal/power test, surface-imperfection inspection and spectral measurement |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |

| Maximum Part Size | 533 x 533 mm | Abrisa edge grinding/polishing program |
| Dimensional Tolerance | ±0.254 mm; up to ±0.05 mm for parts 127 x 127 mm or smaller | Abrisa edge program |
| Parallelism | ±0.0127 mm | Swift edge-finishing equipment; converted from 0.0005 in |
| Design item | What must be reviewed |
|---|---|
| Thickness and part envelope | 0.813 mm 50.8 mm 19.05 x 19.05 mm 533 x 533 mm |
| Tooling and process condition | Swift states that edge grinding and profiling are supported by 3-axis and 4-axis CNC workstations. |
| Tolerance and finish | ±0.254 mm; up to ±0.05 mm for parts 127 x 127 mm or smaller Swift states that the refined edge may be a smooth matte finish or an optically clear high-gloss luster. |
| Drawing review | For Glass Edge Grinding on Glass Lens, identify the glass grade, datums, processed features, edge and surface zones, quantity and inspection method. |
Inspection Focus for Glass Lens Edge Grinding
Inspect the processed feature together with adjacent edges, surfaces, wall sections and functional zones.
| Review item | Project-specific focus |
|---|---|
| Process defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Process limitation | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Design condition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Product design risk | Wrong glass melt data, centration error, edge stress, coating mismatch and cosmetic-system ambiguity |
| Product inspection | Interferometry, centration, focal/power test, surface-imperfection inspection and spectral measurement |
| Acceptance method | Scratch-Dig Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
