This machine shop is designed for rapid turnaround of precision prototypes requiring tight geometric tolerances, complex 3D contours, and high repeatability. Processes are supported by full metrology and first-article inspection (FAI) documentation per AS9102 or customer-specific requirements. Material certifications and traceability are standard for metals; moisture conditioning and stress-relief protocols are applied for engineering plastics.
From CAD to Part: The Process
Honyo Prototype executes a streamlined, technology-driven workflow for CNC machining prototypes designed to minimize lead time while ensuring manufacturability and quality. Our five-stage process begins with CAD file ingestion and concludes with certified delivery, integrating AI and engineering expertise at critical junctures.
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid preferred) via our secure customer portal. The system validates file integrity and geometry completeness, rejecting submissions with missing datums, unresolved features, or incompatible units to prevent downstream errors. This automated check ensures only production-ready designs enter quotation.
The AI Quote engine then processes the validated CAD model using machine learning algorithms trained on 15+ years of Honyo shop floor data. It analyzes geometric complexity, material requirements, tolerance density, and feature counts against real-time machine availability and labor rates. Unlike basic online calculators, our AI factors in secondary operations like deburring or anodizing, generating a detailed cost breakdown within 90 seconds. Quotes include estimated machining hours, material waste factors, and expedited pricing tiers based on current shop load.
Engineering review follows immediately after quote acceptance through our Digital Manufacturing Feedback (DFM) phase. A dedicated manufacturing engineer performs a rigorous analysis focusing on geometric feasibility, tool accessibility, and cost drivers. Critical DFM findings are communicated through a structured report:
| DFM Focus Area | Typical Feedback Example | Client Impact |
|---|---|---|
| Tolerance Optimization | Suggest relaxing ±0.005″ to ±0.010″ on non-mating surfaces | 22% cost reduction, 35% faster cycle time |
| Feature Manufacturability | Recommend minimum hole depth of 3x diameter for 1/8″ drills | Eliminates custom tooling costs |
| Material Utilization | Propose nesting adjustment to fit two parts per 4″x4″ billet | Reduces material cost by 40% |
| Secondary Operations | Identify unnecessary chamfers requiring manual deburring | Cuts post-processing time by 1.5 hours |
This collaborative phase typically resolves 85% of manufacturability issues before metal cutting begins, with engineers available for direct consultation via portal messaging.
Production occurs in our climate-controlled facility using Haas and DMG MORI CNC centers (3-axis to 5-axis milling/turning) with real-time tool wear monitoring. Each job receives a unique digital work order triggering automated material kitting from our segregated alloy inventory (aluminum 6061-T6, 7075; stainless 303, 316; titanium Ti-6Al-4V). In-process inspections verify critical dimensions at 25%, 50%, and 75% completion milestones using CMM and optical comparators, with data logged to the client’s digital twin.
Final delivery includes machined parts packaged with anti-corrosion protection, a full FAIR (First Article Inspection Report) certifying AS9102 compliance, and a digital quality dossier via our portal. Standard lead time is 7-10 business days from DFM sign-off, with expedited 72-hour service available for qualified geometries. All shipments include real-time logistics tracking and a post-delivery engineering debrief to capture lessons learned for future iterations. This closed-loop system reduces prototype iteration cycles by 50% compared to traditional machine shops through embedded manufacturability intelligence at every stage.
