How the Process and Glass Type Interact
The table separates verified process or material records from project-specific items that still require drawing review.
| Review area | Assigned technical basis |
|---|---|
| Process purpose | Glass Drilling: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Material or functional basis | Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements |
| Input form | Flat sheet, blank, tube, rod or preform as applicable to the named process |
| High-risk condition | Thin, brittle, strengthened, crystalline or coated parts require grade- and geometry-specific qualification |
| Inspection basis | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |

Inspection Focus for Heat Resistant Glass glass drilling Feasibility Review
Acceptance should connect the drawing characteristic to a measurement method, fixture condition and stated limit.
| 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 |
| Acceptance method | Microscopic Edge Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
