Design for Machining: CNC DfM Guidelines
A manufacturability-first approach prioritizes tool access, rigid features, and tolerances that support test objectives.
Automated DfM feedback at upload flags tool access, wall thickness, and other risks so you can refine the 3D model before production. UYEE helps match multi-axis selection to the geometry instead of forcing a 3-axis setup to approximate a 5-axis method.
Geometry, tool access, and feature sizing for 3–5 axis
Keep walls appropriately thick and features within cutter reach. Minimum wall thickness depends on material, but designing broader webs reduces chatter and tool deflection.
Use radiused fillets at internal corners to allow proper cutter engagement. Deep, small pockets should be designed with access ramps or additional setups in mind.
Tolerance planning for appearance vs functional parts
Separate cosmetic and functional tolerances upfront. Tight form tolerances belong on interfaces. Looser cosmetic limits cut cost and reduce cost.
Define datum schemes and tolerance stacks for assemblies and kinematic mechanisms. Document measurement plans for critical features so acceptance criteria are well-defined before the first run.
- Set minimum wall thickness, feature depths, and fillets to enhance tool access and stability.
- Use 5-axis when feature relationships or undercuts need single-setup accuracy; choose simpler fixtures when speed matters.
- Specify best practices for threads, countersinks, and small holes to prevent tool deflection and deliver repeatable quality.
- Early DfM reviews reduce redesign cycles and speed prototyping iterations.
| Focus | Design Rule | Benefit |
|---|---|---|
| Wall & Fillet | Wider webs, radiused corners | Reduced deflection, better surface finish |
| Setups | Prefer 5-axis for complex relations | Fewer fixtures, preserved geometry |
| Tolerances | Functional vs cosmetic | Cost control, faster cycles |

| Run size | 1–200 units | Validation, pilot trials |
| Quality & docs | FAI, CoC, inspection reports | Regulated tests, production handoff |
| Flexibility | Fast reorders, design revisions | Iteration-driven development |
CNC vs Injection Molding and 3D Printing for Prototypes
Choosing the right fabrication route can save weeks and budget when you move from concept to test parts.
Small batches require a practical decision: avoid long lead times or accept tooling for lower unit cost. For many low-quantity runs, machined parts outperform molds on schedule and upfront cost. Printing is fastest for concept visuals and complex internal lattices, but may not match mechanical performance.
Cost, time, and fidelity trade-offs at low quantities
Injection molding demands tooling that can take months and significant budget in cost. That makes it hard to justify for small lots.
Machined parts eliminate tooling and often provide tighter dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are reclaimed to reduce waste.
- Time: printing for hours to days; machining for days; injection may take weeks to months.
- Cost: low unit counts favor machining or printing; molding only pays off at volume.
- Fidelity: machining delivers consistent tolerances and surface finish; printing can show anisotropy and layer artifacts.
When to bridge from CNC prototypes to molding
Plan a bridge to injection when the design is stable, tolerances are stable, and material choice is finalized. Use machined parts to validate fit, function, and assembly before committing to a mold.
Early DfM learnings from machined runs reduce mold changes and increase first-off success. Right-size raw stock, nest efficiently, and reclaim chips to improve sustainability during the transition.
| Attribute | Best for | Notes |
|---|---|---|
| Printing | Ultra-fast concepts, complex lattices | Low strength; good for visual and some functional tests |
| Machining | Small lots, tight tolerances, mechanical tests | Avoids tooling; recyclability reduces waste |
| Injection | High-volume production | High upfront tooling; lowest unit cost at scale |
Beyond CNC: Adjacent On-Demand Manufacturing
Modern development needs a suite of on-demand methods that fit each milestone.
UYEE Prototype augments its offering with sheet metal, high-resolution 3D printing, and rapid injection molding to cover the full range of development needs.

3D printing and SLA
SLA printing provides smooth surfaces and fine detail for concept models and complex internal geometries. It supports speedy visual checks and fit trials before moving to harder materials.
Rapid injection molding
Rapid tooling, family molds, and multi-cavity options enable bridging to higher volumes once designs are stable. Overmolding can add soft-touch or bonded layers in the same run.
Multi-process programs often combine CNC parts with printed components or sheet metal to accelerate subsystem integration. Material and process selection prioritize validation goals, schedule, and budget.
- Sheet metal: fast iterations for formed parts and brackets.
- SLA printing: high-accuracy surfaces and internal detail.
- Rapid molding: cost-effective bridge when volumes justify tooling.
| Method | Best use | Key benefit |
|---|---|---|
| Sheet metal | Enclosures, brackets | Fast flat-pattern changes |
| SLA printing | Concept and internal features | Smooth finish, fine detail |
