Technical Capabilities
CNC machining of aircraft parts requires high precision, repeatability, and adherence to strict aerospace standards due to the critical nature of flight components. Multi-axis milling (3, 4, and 5-axis) and CNC turning are commonly used to produce complex geometries with tight tolerances. Materials are selected based on strength-to-weight ratio, corrosion resistance, and thermal performance. Below is a detailed technical specification table outlining key parameters for CNC machining in aircraft part production.
| Parameter | 3-Axis Milling | 4-Axis Milling | 5-Axis Milling | CNC Turning | Notes |
|---|---|---|---|---|---|
| Axis Configuration | X, Y, Z linear axes | X, Y, Z + one rotary (A or B) | X, Y, Z + two rotary (typically A & B) | X, Z linear + C-axis (rotary spindle) | 5-axis enables simultaneous tool movement on all axes for complex contours |
| Typical Applications | Flat plates, housings, brackets | Impeller hubs, angled flanges | Turbine blades, structural brackets, complex contours | Shafts, bushings, fasteners, cylindrical parts | 5-axis reduces need for multiple setups |
| Tolerance Capability | ±0.001″ (0.025 mm) | ±0.001″ (0.025 mm) | ±0.0005″ (0.0127 mm) | ±0.0005″ to ±0.001″ (0.0127–0.025 mm) | Tight tolerances align with AS9100 and NADCAP requirements |
| Surface Finish (Typical) | 32–64 μin RA | 32–64 μin RA | 16–32 μin RA | 16–64 μin RA | Finishing passes and tool selection critical for fatigue life |
| Materials – Aluminum | 2024, 6061, 7075 | 2024, 6061, 7075 | 2024, 6061, 7075 | 2024, 6061, 7075 | High strength-to-weight; commonly anodized or clad |
| Materials – Steel | 4130, 4340, 17-4 PH | 4130, 4340, 17-4 PH | 4130, 4340, 17-4 PH, A286 | 4130, 4340, 15-5 PH | Used for high-stress, high-temp applications; often heat-treated |
| Materials – ABS | Limited use (non-structural) | Prototyping, jigs, fixtures | Non-flight components, mockups | Not typical | Used in non-critical, low-temp environments |
| Materials – Nylon | Bushings, insulators, wear parts | Guide components, spacers | Custom insulators, non-metallic fittings | Bushings, washers, sleeves | Self-lubricating; good wear resistance |
| Spindle Speed Range | 8,000–20,000 RPM | 8,000–20,000 RPM | 10,000–30,000 RPM | 1,500–6,000 RPM (high precision) | Higher speeds for aluminum and finishing |
| Positioning Accuracy | ±0.0002″ (0.005 mm) | ±0.0002″ (0.005 mm) | ±0.0001″ (0.0025 mm) | ±0.0001″ (0.0025 mm) | Verified via laser calibration (per ISO 230-2) |
| Work Envelope (Typical) | Up to 40″ x 20″ x 20″ | Up to 40″ x 20″ x 20″ + 360° rotation | Up to 30″ x 30″ x 25″ with full A/B rotation | Ø2″ to Ø12″ bar stock, up to 12″ length | Larger parts may require multi-setup or gantry systems |
All processes are performed under controlled environments with strict process validation, first article inspection (FAI), and full traceability per AS9100 and FAA regulations. In-process probing, tool length compensation, and thermal compensation systems are standard to maintain tight tolerance consistency. Material certifications (e.g., AMS, MIL specs) and post-machining treatments (e.g., stress relief, shot peening, anodizing) are integral to final part qualification.
From CAD to Part: The Process
Honyo Prototype CNC Machining Process for Aircraft Parts
Honyo Prototype executes a rigorously controlled CNC machining workflow for aircraft components, adhering to AS9100 Rev D and NADCAP standards. The process begins with CAD Upload, where clients submit native 3D models (STEP/IGES preferred) via our secure portal. We require geometric dimensioning and tolerancing (GD&T) per ASME Y14.5, material specifications (e.g., AMS 4928 for Ti-6Al-4V), and surface finish callouts. Non-conforming files trigger automated notifications for revision prior to progression.
AI-Powered Quoting follows immediately, leveraging our proprietary algorithm trained on 15,000+ aerospace builds. The system analyzes part complexity, material waste factors, fixture requirements, and machine time while cross-referencing real-time material costs (e.g., 7075-T7351 aluminum bar stock) and NADCAP-certified secondary process pricing. Quotes include explicit compliance notes—such as “Requires AMS 2750F heat treat documentation” or “Nadcap AC7102/10 non-destructive testing mandatory”—within 2 business hours.
Design for Manufacturability (DFM) Review is conducted by our AS9102-certified engineering team. We identify critical aerospace-specific risks:
Geometric instabilities in thin-walled structures (<0.5mm tolerance zones)
Inaccessible tool paths for complex 5-axis geometries (e.g., turbine blade contours)
Material grain flow implications for forged blanks per AMS 4820
Regulatory gaps against FAA Part 21 or EASA 21A.903 airworthiness standards
Clients receive a formal DFM report with actionable recommendations, typically reducing lead time by 18–22% through feature optimization.
Precision Production occurs in our climate-controlled Class 8 cleanroom facility. Key stages include:
Material Verification: Incoming stock validated via PMI (Positive Material Identification) and traceability to mill test reports (e.g., EN 10204 3.1)
Machining: 5-axis milling/turning on DMG MORI machines with real-time tool wear monitoring; in-process CMM checks at critical datum points per inspection plan
Post-Processing: Mandatory shot peening (AMS 2430) or anodizing (AMS 2471) with Nadcap-accredited partners
First Article Inspection (FAI): Complete AS9102B Form 1/2/3 documentation, including 3D scan deviation reports against nominal CAD
Certified Delivery encompasses more than physical shipment. All aircraft parts ship with:
Full traceability package (material certs, process logs, non-conformance reports if applicable)
PPAP Level 3 documentation per customer-specific requirements
MIL-STD-130-compliant UID marking applied via laser etching
Vacuum-sealed packaging meeting IPC-1601 moisture sensitivity standards
Final delivery includes digital access to all quality records via our cloud-based QMS portal, with physical parts dispatched via DHL Aviation with real-time tracking.
This end-to-end process ensures zero regulatory non-conformities across 98.7% of aerospace builds, with typical lead times of 10–15 days for prototype quantities. All stages are audited quarterly under our AS9100 certification, with material test reports archived for 30+ years per FAA 14 CFR §21.182.
