Technical Capabilities

Precision machining for aerospace applications demands high accuracy, repeatability, and adherence to strict quality standards due to the critical nature of flight-critical components. Multi-axis milling (3, 4, and 5-axis) and precision turning are commonly employed to produce complex geometries with tight tolerances. These processes are optimized for a range of aerospace-grade materials including aluminum alloys, stainless and alloy steels, and engineering thermoplastics such as ABS and nylon, which are used in non-structural or interior applications.

From CAD to Part: The Process

Honyo Prototype Precision Machining Process for Aerospace Components

Our end-to-end precision machining workflow for aerospace applications is engineered to meet AS9100 standards, ensuring zero-defect delivery while optimizing time-to-market. The process begins with rigorous digital validation and concludes with full traceability documentation, critical for FAA/EASA compliance. Below is the detailed sequence:

CAD Upload and Validation
Clients submit native CAD files (STEP, IGES, or Parasolid) via our secure portal. Our system performs automated geometric integrity checks, verifying units, scale, and manufacturability against aerospace material constraints (e.g., Inconel 718, Ti-6Al-4V). Files failing validation trigger immediate client alerts with specific error diagnostics, preventing downstream delays. All data is encrypted per ITAR requirements.

AI-Powered Quoting with Engineering Oversight
Proprietary AI analyzes the validated CAD model against our 15,000+ aerospace part database, generating a preliminary quote in under 90 minutes. The algorithm factors in material waste, machine time, fixture complexity, and surface finish requirements (e.g., Ra 0.8 µm for hydraulic manifolds). A Senior Manufacturing Engineer then reviews the AI output, adjusting for non-geometric variables like first-article inspection (FAI) protocols or special NDT requirements. Clients receive a formal quote with cost breakdown and lead time commitment.

Collaborative DFM Analysis
Upon quote acceptance, our DFM team conducts a joint review with the client’s engineering staff. We identify high-risk features such as thin-wall sections (<0.5mm), deep cavities requiring specialized tooling, or tolerance stacks exceeding ±0.005mm. Using simulation software (e.g., Mastercam Simulator), we propose actionable modifications—like adding draft angles to blind holes—to eliminate chatter or thermal deformation during milling. All suggestions include tolerance impact assessments, documented in a formal DFM report requiring client sign-off.

Precision Production Execution
Machining occurs in climate-controlled cells housing 5-axis DMG MORI and Makino centers with sub-micron positioning accuracy. Key protocols include:
Material Traceability: Each billet tagged with QR-linked mill certificates (e.g., AMS 4928 for titanium).
In-Process Verification: On-machine probing checks critical dimensions after roughing/final passes.
Thermal Management: Coolant temperature stabilized to ±1°C to prevent dimensional drift.
Cleanroom Assembly: For subassemblies, Class 10,000 environments prevent particulate contamination.

Certified Delivery and Documentation
Parts undergo final inspection per AS9102B FAI requirements using calibrated CMMs (e.g., Zeiss CONTURA), with full GD&T reporting. Delivery includes:
Dimensional results cross-referenced to drawing annotations
Material test reports with lot-specific chemistry
NDT documentation (e.g., fluorescent penetrant inspection for castings)
PPAP Level 3 package upon request
All components ship in ESD-safe containers with serialized tracking, meeting ITAR shipping protocols.

Aerospace Tolerance Capabilities
| Feature Type | Standard Industry Tolerance | Honyo Prototype Capability |
|——————–|—————————–|—————————|
| Linear Dimensions | ±0.025 mm | ±0.003 mm |
| Geometric (GD&T) | ±0.05 mm | ±0.01 mm (position/runout)|
| Surface Finish (Ra)| 1.6 µm | 0.4 µm (mirror polishing) |

This closed-loop process reduces aerospace prototype lead times by 35% versus industry averages while maintaining 99.98% first-pass yield rates, directly supporting clients’ critical path schedules for certification and production ramp-up. All steps are audited under our AS9100 Rev D QMS, with real-time client access to production dashboards.
