Feature-specific approval
Tool access, wall section, edge distance, finish, datums, tolerance and inspection method must be approved for the actual drawing.
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 Grooving: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Product geometry | Through bore, counterbore or concentric stepped OD/ID |
| Typical input form | Flat sheet, blank, tube, rod or preform as applicable to the named process |
| Process limitations | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Inspection basis | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |
Glass Bushing Features That Affect the Process
Product-form records describe typical geometry and inspection needs; the supplied glass grade and drawing remain controlling inputs.
| Product requirement | What to define |
|---|---|
| Geometry and available forms | Through bore, counterbore or concentric stepped OD/ID |
| Dimensions and thickness | State outer dimensions, thickness, diameters, lengths, OD/ID and datum scheme as applicable. |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Ground or polished ends with protective chamfer |
| Inspection | OD/ID measurement, wall map, concentricity, end squareness and edge microscopy |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |
Glass Grooving References and Design Limits
Numeric values appear only when verified public process evidence is assigned. Proxy-family pages intentionally suppress numeric ranges.
| Process parameter | Reference value | Applicable condition |
|---|---|---|
| Minimum Thickness | 0.76 mm | JNS/Abrisa CNC fabrication program |
| Maximum Thickness | >25.4 mm | JNS/Abrisa CNC fabrication program; upper limit stated as greater than 25.4 mm |
| Minimum Part Size | 50.8 x 50.8 mm | CNC program; workholding may require larger size for individual features |
| Maximum Part Size | 2286 x 1524 mm | CNC program envelope |
| Dimensional Tolerance | ±0.508 mm general; up to ±0.127 mm | Provider CNC program; feature, material and size dependent |
| Design item | What must be reviewed |
|---|---|
| Thickness and part envelope | 0.76 mm >25.4 mm 50.8 x 50.8 mm 2286 x 1524 mm |
| Tooling and process condition | Valley uses 3-, 4- and 5-axis CNC machining for hard and brittle materials. Abrisa states that groove inside dimensions can be tapered or seamed. |
| Tolerance and finish | ±0.508 mm general; up to ±0.127 mm |
| Drawing review | For Glass Grooving on Glass Bushing, identify the glass grade, datums, processed features, edge and surface zones, quantity and inspection method. |
Inspection Focus for Glass Bushing Grooving Processing
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 | Thin-wall cracking, concentricity error, bore chips and assembly interference |
| Product inspection | OD/ID measurement, wall map, concentricity, end squareness and edge microscopy |
| Acceptance method | Surface Roughness Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
