Design for Machining: Machinability Guidelines
A CNC-aware approach prioritizes tool access, stable features, and tolerances that support test objectives.
Automated DfM feedback at upload identifies tool access, wall thickness, and other risks so you can modify the 3D model before production. UYEE aligns 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 long enough features within the cutter reach. Minimum wall thickness varies by 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 multiple setups in mind.
Tolerance planning for appearance vs functional parts
Separate cosmetic and functional tolerances early. Tight form tolerances belong on critical interfaces. Looser cosmetic limits save time and reduce cost.
Define datum schemes and tolerance stacks for assemblies and kinematic mechanisms. Document measurement plans for critical features so acceptance criteria are clear before the first run.
- Set minimum wall thickness, feature depths, and fillets to improve tool access and stability.
- Use 5-axis when feature relationships or undercuts need single-setup accuracy; choose simple fixturing 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 accelerate 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 |

| Attribute | Typical Range | When to Use |
|---|---|---|
| Lead time | 1–5 days (avg 2 days) | Urgent engineering builds |
| 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
Picking the right method can reduce time and cost when you move from concept to test parts.
Low quantities force a practical decision: avoid long lead times or invest in tooling for lower unit cost. For many low-quantity runs, machined parts outperform molds on schedule and upfront cost. Printing is quickest for concept visuals and complex internal lattices, but may not match mechanical performance.
Cost, time, and fidelity trade-offs at low quantities
Injection molding requires tooling that can take months and significant budget in cost. That makes it uneconomical for small lots.
Machined parts avoid tooling fees and often deliver better dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are reclaimed to improve sustainability.
- 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 frozen, tolerances are stable, and material choice is locked. Use machined parts to prove fit, function, and assembly before cutting a mold.
Early DfM learnings from machined runs cut mold changes and improve first-off success. Optimize raw stock, nest efficiently, and recycle chips to enhance 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: Complementary On-Demand Manufacturing
Modern development benefits from a suite of on-demand methods that fit each milestone.
UYEE Prototype extends its services with sheet metal, high-accuracy 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 fast visual checks and fit trials before committing 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 mix CNC parts with printed components or sheet metal to speed subsystem integration. Material and process selection focus on 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 |
| Rapid molding | Bridge volumes | Production-like parts, repeatability |
