From CAD to Part: The Process
Honyo Prototype Precision Milling Process Overview
Honyo Prototype executes China-based precision milling through a rigorously structured workflow designed for technical accuracy, cost transparency, and accelerated time-to-market. This integrated process leverages advanced automation while maintaining critical human engineering oversight at each phase.
CAD Upload and Initial Processing
Clients initiate the workflow by uploading native or neutral CAD formats including STEP, IGES, or Parasolid via Honyo’s secure customer portal. The system performs immediate geometric validation to confirm file integrity and manufacturability baseline. Non-conforming files trigger automated notifications detailing required corrections, ensuring only production-ready geometry advances to quoting.
AI-Powered Quoting with Engineering Validation
Uploaded geometry enters Honyo’s proprietary AI quoting engine, which analyzes 200+ technical parameters including material utilization, feature complexity, tolerance density, and machine time estimates. The AI generates a preliminary cost model within 90 minutes, but this output undergoes mandatory review by our Shenzhen-based manufacturing engineers. Engineers validate AI assumptions against real-time machine availability, tooling constraints, and material market fluctuations, adjusting quotes for technical feasibility before client delivery.
Collaborative DFM Analysis
Upon quote acceptance, Honyo’s DFM phase begins as a structured engineering dialogue rather than a unilateral review. Our team conducts tolerance stack analysis, identifies high-cost micro-features (e.g., internal radii <0.5mm), and evaluates fixturing challenges using NX CAM simulations. Clients receive a formal DFM report within 24 hours detailing actionable recommendations such as suggested tolerance relaxations or feature modifications that typically reduce costs by 18–35% without compromising function. This phase requires explicit client sign-off before production release.
Precision Production Execution
All milling occurs in Honyo’s ISO 9001:2015-certified Shenzhen facility using Makino V56 5-axis centers with sub-micron linear encoders. Production follows a documented control plan:
First-article inspection validates critical dimensions via Zeiss CONTURA CMM before batch commencement.
In-process checks at 25% and 75% completion monitor thermal drift and tool wear using Renishaw probes.
Final inspection certifies all features against ASME Y14.5 GD&T standards, with full FAIR documentation provided.
Global Delivery Management
Completed parts undergo vacuum desiccant packaging with humidity indicators for moisture-sensitive components. Honyo manages end-to-end logistics under DDP (Delivered Duty Paid) terms, providing clients with real-time shipment tracking via integrated DHL/FedEx APIs. Typical lead times range from 7–12 business days for 1–100 units depending on complexity, with expedited options available. All deliveries include digital quality dossiers containing CMM reports, material certs, and process validation records accessible through the client portal.
This closed-loop methodology ensures dimensional repeatability to ±0.005mm while maintaining audit-ready traceability from CAD file to delivered product, addressing core B2B requirements for quality governance and supply chain transparency in precision manufacturing.
