Design for Machining: Machinability Guidelines

A CNC-aware approach focuses on tool access, rigid features, and tolerances that match test needs.

Automated DfM feedback at upload flags 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 thick enough for rigidity and features within cutter reach. Minimum wall thickness depends on material, but designing wider 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 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 well-defined 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 single-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 reduce redesign cycles and accelerate prototyping iterations.

Speed to Market: Lead Times and Low-Volume Runs

Rapid builds compress calendar gaps so engineers can progress to testing quickly.

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

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

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

Reliable delivery rhythm helps synchronize test plans, firmware updates, and supplier readiness so programs stay on schedule.

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 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 significant budget in cost. That makes it hard to justify for small lots.

Machined parts avoid tooling fees and often deliver tighter dimensional control and stronger material behavior 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 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 stable, and material choice is locked. Use machined parts to validate fit, function, and assembly before tooling up.

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

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-resolution 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 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 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 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.
