Technical Specifications for Custom Aluminum Pieces

Prepared by: Senior Manufacturing Engineer, Honyo Prototype
Precision Machining | Tight-Tolerance Expertise | Multi-Axis Capabilities

As a senior engineer at Honyo Prototype, I oversee the production of high-precision custom components. Below are detailed technical specs for aluminum parts (our primary focus), with notes on how we handle steel, ABS, and nylon where applicable. All capabilities adhere to ISO 9001:2015 standards, with tight-tolerance tolerances achievable through advanced process control.

1. Milling Capabilities (3-Axis, 4-Axis, 5-Axis)

| Parameter | Specification | Notes for Aluminum |
|——————–|——————————————————————————-|———————————————————————————–|
| Machine Types | Haas VF-2SS (3-axis), DMG MORI CTX 400 (4-axis), DMG MORI CTX 500 (5-axis) | All machines feature RTCP (Rotary Tool Center Point) for true 5-axis contouring. |
| Tolerance | ±0.0005″ (±0.0127 mm) for critical features; ±0.001″ (±0.0254 mm) for general features | Tighter tolerances (e.g., ±0.0002″) possible via secondary grinding for aerospace/medical parts. |
| Surface Finish | Ra 16–32 μin (0.4–0.8 μm) standard; Ra ≤ 8 μin (0.2 μm) achievable with fine finishing | Optimized with high-speed machining (HSM) and coolant systems to prevent thermal distortion. |
| Max Part Size | 3-axis: 48″ x 24″ x 24″; 5-axis: 31.5″ x 23.6″ x 19.7″ | Larger parts handled via modular fixturing or staged machining. |
| Key Processes | – 3-axis: Flat surfaces, simple contours.
– 4-axis: Rotational features (e.g., flanges, slots).
– 5-axis: Complex geometries (e.g., turbine blades, aerospace fixtures) with single-setups. | 5-axis minimizes re-fixturing, reducing cumulative error. Ideal for tight-tolerance assemblies. |

3. Tight Tolerance Guidelines

Achievable Tolerances for Aluminum:
±0.0005″ (±0.0127 mm): Standard for critical dimensions (e.g., bearing fits, mating surfaces).
±0.0002″ (±0.005 mm): Possible for high-end applications (e.g., aerospace, medical implants) with:
- Temperature-controlled machining rooms (±2°C).
- In-process laser measurement and adaptive compensation.
- Secondary operations (e.g., honing, lapping) for sub-micron precision.
Critical Factors Affecting Tolerance:
Part Size: Larger parts (>12″) may have looser tolerances (±0.001″) due to thermal expansion.
Geometry: Thin walls (<0.030″) or tall features require specialized fixturing to prevent deflection.
Material: Aluminum alloys (e.g., 6061, 7075) are stable; 2024 requires stress-relief annealing to avoid warpage.
Design for Manufacturability (DFM) Tips:
Avoid sharp internal corners (use 0.015″ radius minimum).
Specify tolerances only on critical features (non-critical areas: ±0.005″).
Use datum features consistently across all drawings.

4. Material Specifications

We machine aluminum as our primary focus, but also handle steel, ABS, and nylon with adjusted processes:

| Material | Typical Alloys/Types | Machining Notes | Tight Tolerance Feasibility |
|———-|—————————|———————————————————————————|—————————-|
| Aluminum | 6061-T6, 7075-T6, 2024-T3, 5052-H32 | – Optimal for high-speed machining.
– Use coolant to prevent thermal distortion.
– Anodizing possible post-machining. | ★★★★★ (±0.0005″ standard) |
| Steel | 1018, 4140, 304SS, 17-4PH | – Slower speeds (50–150 SFM) due to hardness.
– Carbide tooling required for hardened steels.
– Stress-relieving often needed for precision. | ★★★★☆ (±0.0005″ achievable; ±0.0002″ requires grinding) |
| ABS | Standard grades (e.g., ABS 110) | – Low-speed machining (20–50 SFM) to avoid melting.
– Dry cutting preferred; no coolant (causes crazing).
– Thermal expansion: ±0.002″ typical due to plasticity. | ★★☆☆☆ (±0.002″ standard; tighter tolerances risky without stabilization) |
| Nylon | 6/6, 6/12, Acetal (POM) | – Ultra-low speeds (10–30 SFM); minimal tool pressure.
– Moisture-sensitive (pre-dry parts to <0.2% humidity).
– High risk of warpage; tight tolerances require post-machining stabilization. | ★☆☆☆☆ (±0.003″ typical; ±0.001″ only for small, simple parts) |

Note on Non-Aluminum Materials: While we machine steel, ABS, and nylon, aluminum remains our specialty for tight-tolerance work due to its stability, machinability, and predictable thermal behavior. For plastics (ABS/Nylon), we recommend design adjustments (e.g., larger tolerances, thicker walls) to ensure reliability.

5. Quality Assurance

In-Process Checks: CMM inspections at 25%, 50%, and 100% completion.
Final Inspection: AS9102 FAI reports for aerospace; ISO 17025-certified measurements for all parts.
Traceability: Full lot traceability via our ERP system (Barcodes on fixtures + parts).

From CAD to Part: The Process

Honyo Prototype – Custom Aluminum Parts Workflow
(what happens after you click “Upload CAD” until the box reaches your dock)

Upload CAD
• Portal accepts any mix of .step, .iges, .x_t, .sldprt, .3mf, .stl
• Geometry engine auto-repairs minor translation errors and flags impossible features (zero-thickness walls, non-manifold edges, reversed normals).
• Within 30 s you receive a checksum report: volume, bounding box, projected area, # of features, # of setups we will need.
AI Quote (60-second turnaround)
• Neural-net pricing model trained on 1.8 M historical aluminum jobs (CNC, die-cast, sheet, extrusion + secondary).
• Inputs: material alloy, machine cycle-time estimator, tool-wear predictor, shop-floor load, raw-stock LME price, anodize type, finish area.
• Outputs: piece price, batch price curves (1, 5, 20, 100, 500), lead-time confidence bands, CO₂ footprint.
• You can adjust quantity, alloy, finish, or tolerances and watch price/lead-time re-calculate in real time.
DFM (Design-for-Manufacturing) – 4-hour human review
• A senior manufacturing engineer (that’s me) opens the AI pre-analysis and validates:
– Tolerances vs. process capability (CNC ± 0.025 mm, 5-axis ± 0.01 mm, die-cast ± 0.1 mm).
– Internal radii ≥ 0.3 mm for end-mills, ≥ 1 mm for die-cast pull.
– Undercuts, deep pockets, aspect ratios, tool accessibility.
– Anodize racking points, masking requirements, weld prep, leak-test paths.
• We send a 1-page DFM pdf: recommended changes, cost impact of accepting or rejecting each, revised 3D with ghosted “before vs. after”.
• Customer approves or negotiates; when you click “Accept DFM” the job is frozen and ERP releases BOM and routing.
