From CAD to Part: The Process
Honyo Prototype Precision Engineering Machining Workflow
Honyo Prototype delivers end-to-end precision engineering machining services through a rigorously defined workflow designed to minimize lead times, ensure manufacturability, and guarantee component quality. This process integrates digital tools with expert engineering oversight, specifically structured for complex, low-to-medium volume prototyping and production runs.
CAD Upload and Initial Processing
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid) via our secure customer portal. Our system automatically validates file integrity, extracts critical geometric data, and identifies key manufacturing features such as tight tolerances, thin walls, or complex contours. All data is encrypted and quarantined for confidentiality, adhering to ISO 27001 standards. This phase ensures the digital model aligns with our machining capabilities before proceeding.
AI-Powered Quoting Engine
Uploaded CAD data is processed through Honyo’s proprietary AI quoting engine, trained on 15+ years of machining logs and real-time machine utilization data. The system analyzes material removal volume, feature complexity, toolpath density, and fixture requirements to generate an accurate cost and lead time estimate within 2 business hours. Unlike basic online calculators, our AI cross-references historical data on material behavior (e.g., Inconel 718 work-hardening rates) and machine-specific constraints (e.g., 5-axis vs. Swiss lathe limitations). The quote includes a preliminary feasibility flag for geometric challenges, such as aspect ratios exceeding 10:1.
Engineering-Led DFM Analysis
Upon quote acceptance, Honyo’s manufacturing engineering team conducts a formal Design for Manufacturability (DFM) review. This is not an automated step but a collaborative human-AI process where engineers use simulated machining validation software to identify risks like:
Non-optimal wall thicknesses causing chatter in aluminum 6061
Unmachinable internal radii below 0.5mm in hardened steel
Suboptimal stock allowances increasing cycle time by >15%
We provide a detailed DFM report with actionable recommendations, such as adjusting fillet radii or suggesting alternative materials (e.g., switching from Ti-6Al-4V to Ti-5553 for improved machinability in high-volume runs). Client approval of the DFM report is mandatory before production to prevent costly revisions.
Precision Production Execution
Approved designs move to our climate-controlled machine shop, where work is allocated based on real-time machine availability and technical fit:
| Machine Type | Typical Applications | Tolerance Capability |
|---|---|---|
| 5-Axis Milling | Aerospace impellers, medical implants | ±0.005 mm |
| Swiss-Type Lathes | Micro-medical components, fuel system parts | ±0.002 mm |
| Wire EDM | Tooling inserts, hardened steel features | ±0.001 mm |
All processes follow documented work instructions with in-process gauging at critical stages. For example, titanium aerospace brackets undergo laser interferometer verification after roughing to prevent thermal distortion in finishing. Material certifications (e.g., EN 10204 3.1 for stainless steel) and first-article inspection reports (FAIR) per AS9102 are generated for traceability.
Quality-Controlled Delivery
Final components undergo comprehensive metrology in our ISO 17025-accredited lab. Critical dimensions are verified using calibrated CMMs (e.g., Zeiss CONTURA), surface roughness testers, and optical comparators. We deliver with:
Full dimensional inspection report (including GD&T callouts)
Material test certificates
Process validation data (e.g., spindle load monitoring logs)
Packaging certified for shock and humidity per customer specifications
Shipments include serialized tracking with real-time logistics updates, and all documentation is archived for 10 years to support regulatory audits in medical or aerospace sectors.
This integrated workflow reduces time-to-part by 30–50% compared to traditional quoting cycles while ensuring first-pass yield rates exceed 98.5% through proactive DFM intervention. Honyo’s process is certified to AS9100D and ISO 9001:2015, with continuous improvement driven by closed-loop feedback from production data to our AI quoting models.
