Design for Machining: Machinability Guidelines

A manufacturability-first 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 adjust 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 multiple 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 cut cost 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 improve 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 reduce redesign cycles and speed prototyping iterations.

Speed to Market: Lead Times and Low-Volume Runs

Rapid builds compress calendar gaps so engineers can advance from idea to test faster.

UYEE supports rapid prototyping with avg. lead time down to 2 days. Rapid scheduling and standardized setups cut 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 one-off parts.

Teams can reorder or revise parts quickly as development learning accumulates. Tactical use of CNC allows deferring expensive tooling until the design matures, minimizing sunk cost.

Reliable delivery rhythm aligns test plans, firmware updates, and supplier readiness so programs remain on track.

CNC vs Injection Molding and 3D Printing for Prototypes

Picking the right method can cut weeks and costs when you move from concept to test parts.

Low quantities force a practical decision: avoid long waits or invest in 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 demands tooling that can take months and thousands in cost. That makes it uneconomical for small lots.

Machined parts avoid tooling fees and often provide tighter dimensional control and stronger bulk properties than many printed parts. Chips from metal removal are recyclable 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 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 locked. Use machined parts to validate fit, function, and assembly before cutting a mold.

Early DfM learnings from machined runs cut mold changes and increase first-off success. Optimize raw stock, nest efficiently, and recycle 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 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.
