Design for Machining: CNC DfM Guidelines

A manufacturability-first approach prioritizes tool access, stable features, and tolerances that meet test goals.

Automated DfM feedback at upload flags 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 instead of 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 depends on material, but designing broader webs reduces chatter and tool deflection.

Use radiused 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 mating surfaces. 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 improve 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 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

CNC vs Injection Molding and 3D Printing for Prototypes

Selecting the best process can reduce time and cost when you move from concept to test parts.

Small batches force a practical decision: avoid long lead times or invest in tooling for lower unit cost. For many low-quantity runs, machined parts beat 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 months and significant budget in cost. That makes it hard to justify 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 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 tooling up.

Early DfM learnings from machined runs cut mold changes and increase first-off success. Right-size raw stock, optimize nesting, 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
