Mark critical surfaces
Identify sealing faces, sliding fits, electrical contact areas and surfaces that need masking or protection.
FINISH PLANNING
Separate appearance from function. Identify what the surface must do, how it should look, and how the finished dimensions will be accepted.
| Finish discussion | What it concerns | What to specify |
|---|---|---|
| As-machined | Visible cutting texture and edge condition | Define surface roughness where function requires it; specify burr removal and edge breaks. |
| Anodizing | Aluminum appearance and surface treatment | State type, color/reference sample, masking and which dimensions apply after treatment. |
| Passivation | Specified stainless-steel surface treatment | State the applicable process requirement, cleanliness and required documentation. |
| Plating | A specified deposited coating | Define coating system, thickness, substrate, masking and final functional dimensions. |
| Blasting / brushing / polishing | Specified texture or visual surface | Identify treated faces, direction or appearance standard, and features that must be protected. |
Planning options, not a blanket process or performance commitment. Availability and the treatment route are confirmed for each drawing and material.
Identify sealing faces, sliding fits, electrical contact areas and surfaces that need masking or protection.
Use a color, texture or approved reference sample where appearance matters. A process name alone does not fully define visual acceptance.
Clarify which dimensions apply after treatment and how coating or material removal affects mating features.
FROM EXAMPLE TO YOUR REQUIREMENT
Use an example to explain your idea.
Your own drawing defines the final specification.
