Design for Machining: Machinability Guidelines

A CNC-aware approach prioritizes tool access, rigid features, and tolerances that meet test goals.

Automatic DfM checks at upload identifies tool access, wall thickness, and other risks so you can refine the 3D model pre-build. UYEE helps match 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 thick enough for rigidity and long enough features within the cutter reach. Minimum wall thickness varies by material, but designing wider webs cuts 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 upfront. Tight form tolerances belong on 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.

• 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 simpler fixtures when speed matters.
• Specify best practices for threads, countersinks, and small holes to limit deflection and ensure repeatable quality.
• Early DfM reviews cut redesign and speed prototyping iterations.

Speed to Market: Lead Times and Low-Volume Runs

Expedited builds shorten schedules so engineers can advance from idea to test faster.

UYEE offers rapid prototyping with average lead times as fast as two days. Rapid scheduling and standardized setups cut lead time for urgent EVT and DVT builds.

Low-volume runs bridge the gap to pilot and enable assembly testing or limited market trials. Short-run parts keep the same inspection, documentation, and traceability as one-off parts.

Teams can reorder or revise parts quickly as development learning accumulates. Tactical use of CNC lets you defer expensive tooling until the design stabilizes, minimizing sunk cost.

Consistent delivery cadence helps synchronize test plans, firmware updates, and supplier readiness so programs remain on track.

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.

Low quantities require a practical decision: avoid long waits or accept tooling for lower unit cost. For many low-quantity runs, machined parts surpass 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 many weeks and thousands in cost. That makes it uneconomical for small lots.

Machined parts eliminate tooling and often provide better dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are recyclable 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 layer 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 finalized. Use machined parts to prove fit, function, and assembly before committing to a mold.

Early DfM learnings from machined runs reduce mold changes and increase first-off success. Optimize raw stock, nest efficiently, and reclaim chips to improve sustainability during the transition.

Beyond CNC: Adjacent On-Demand Manufacturing

Modern development benefits from a suite of on-demand methods that fit each milestone.

UYEE Prototype broadens capability with sheet metal, high-accuracy 3D printing, and rapid injection molding to cover the full range of development needs.

Sheet metal fabrication uses laser cutting and bending for fast flat-pattern iterations. It is ideal for enclosures and brackets with formed features that are difficult or costly to mill.

3D printing and SLA

SLA printing delivers smooth surfaces and fine detail for concept models and complex internal geometries. It enables 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 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.
