Design for Machining: Machinability Guidelines
A DfM-first approach focuses on tool access, stable features, and tolerances that support test objectives.
Automatic DfM checks at upload identifies tool access, wall thickness, and other risks so you can refine the 3D model before production. UYEE aligns multi-axis selection to the geometry rather than forcing a 3-axis setup to mimic 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 generous fillets at internal corners to allow proper cutter engagement. Deep, small pockets should be designed with ramped entries or additional 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 reduce cycle 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.
- Advise on minimum wall thickness, feature depths, and fillets to enhance tool access and stability.
- Use 5-axis when feature relationships or undercuts need one-setup accuracy; choose simple fixturing when speed matters.
- Specify best practices for threads, countersinks, and small holes to prevent tool deflection and ensure repeatable quality.
- Early DfM reviews cut redesign 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 |
Speed to Market: Lead Times and Low-Volume Runs

Teams can reorder or revise parts quickly as development learning builds. Tactical use of CNC allows deferring expensive tooling until the design stabilizes, minimizing sunk cost.
Reliable delivery rhythm aligns test plans, firmware updates, and supplier readiness so programs remain on track.
| 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 waits or accept tooling for lower unit cost. For many low-quantity runs, machined parts beat 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 many weeks and thousands in cost. That makes it hard to justify for small lots.
Machined parts eliminate tooling and often deliver better dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are reclaimed to minimize scrap.
- 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 offers 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 locked, and material choice is locked. Use machined parts to prove fit, function, and assembly before tooling up.
Early DfM learnings from machined runs cut mold changes and improve first-off success. Right-size raw stock, nest efficiently, and reclaim 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 |

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 moving to harder materials.
Rapid injection molding
Rapid tooling, family molds, and multi-cavity options let teams bridge 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.
