How the Drawing Changes the Processing Plan
Base pages do not assign one universal process or tolerance. ANTGLASS selects cutting, drilling, CNC machining, grinding, lapping, polishing, cleaning and inspection steps from the drawing.
| Planning area | What to review |
|---|---|
| Candidate operations | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Material response | Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements |
| Feature geometry | Review holes, slots, cutouts, internal corners, wall sections and edge distance from the drawing. |
| Edge and surface finish | Define visible edges, sealing lands, optical surfaces, coating sides and handling surfaces. |
| Application conditions | State temperature, chemical exposure, loading, sealing, pressure or vacuum where applicable. |
| Inspection route | Define the characteristic, measurement method, fixture and acceptance limit. |
Information Required Before Quotation
State the drawing revision, exact material or approved alternatives, dimensions, quantity, feature geometry, edge and surface requirements, operating conditions and the acceptance method.
RFQ inputs
- Provide a drawing revision, material or grade, quantity, dimensions, tolerances, critical surfaces and the required inspection record.
Failure Risks and Inspection Focus
Inspection is tied to the functional dimensions and surfaces shown on the approved drawing; generic catalogue values do not replace project acceptance criteria.
| Review item | Project-specific focus |
|---|---|
| Acceptance method | Vision Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
