Design for Machining: Machinability Guidelines

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

Automated DfM feedback at upload flags tool access, wall thickness, and other risks so you can modify the 3D model before production. UYEE aligns multi-axis selection to the geometry rather than forcing a 3-axis setup to approximate a 5-axis method.

Geometry, tool access, and feature sizing for 3–5 axis

Keep walls thick enough for rigidity and features within cutter reach. Minimum wall thickness varies by 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 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 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.

• Set 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 prevent tool 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 move from concept to test sooner.

UYEE offers rapid prototyping with avg. lead time down to 2 days. Priority scheduling and standardized setups compress lead time for urgent EVT and DVT builds.

Low-volume runs connect to pilot and enable assembly testing or limited market trials. Short-run parts keep the same inspection, documentation, and traceability as single-unit work.

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

Consistent delivery cadence aligns test plans, firmware updates, and supplier readiness so programs stay on schedule.

CNC vs Injection Molding and 3D Printing for Prototypes

Selecting the best process 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 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 uneconomical for small lots.

Machined parts eliminate tooling and often provide better dimensional control and stronger material behavior 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 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 frozen, tolerances are locked, and material choice is finalized. Use machined parts to validate fit, function, and assembly before cutting a mold.

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

Beyond CNC: Additional On-Demand Manufacturing

Modern development benefits from a suite of on-demand methods that match 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 quick flat-pattern iterations. It is ideal for enclosures and brackets with formed features that are hard or expensive to mill.

3D printing and SLA

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