CNC: access & geometry
Review cutter access, internal corner radii, pocket depth and thin walls. Identify features that need special attention.
Practical starting points for drawings, geometry and manufacturing discussions.
Discuss your projectReview cutter access, internal corner radii, pocket depth and thin walls. Identify features that need special attention.
Discuss orientation, support removal, enclosed cavities and mating surfaces. Choose a material around the intended evaluation.
Define thickness and bend direction. Review holes near bends, hardware, visible faces and assembly access.
| Include | Why it matters |
|---|---|
| Drawing revision & units | Keep the model, PDF and order on the same revision. |
| Critical dimensions & datums | Identify the interfaces and dimensions that control fit. |
| Threads & inserts | Specify thread size, depth, location and any purchased hardware. |
| Material grade & finish | Call out alloy or resin, surface requirements and masking. |
| Inspection & documents | Agree what evidence is needed before production begins. |
| Quantity & destination | Include prototype and repeat quantities, target date and shipping country. |
A visual model helps evaluate proportions and surface detail. Consider resin printing when the objective is presentation.
Review interfaces, material behavior and loading. Discuss machining or functional printing against the test objective.
Freeze the revision and define acceptance checks before planning a batch.
