From CAD to Part: The Process

Honyo Prototype CNC Steel Cutting Process Overview

Honyo Prototype executes CNC steel cutting through a rigorously defined workflow designed for precision, efficiency, and client transparency. This process begins with digital file submission and concludes with certified delivery, integrating automated and human expertise at critical stages to ensure manufacturability and quality. Below is a technical breakdown of each phase.

CAD File Upload and Validation
Clients initiate the process by uploading native CAD files (e.g., STEP, IGES, or native SolidWorks) via our secure portal. Our system performs automated validation checks for file integrity, unit consistency, and geometric completeness. Unsupported formats or corrupted files trigger immediate client notification for resubmission. All data is encrypted per ISO 27001 standards, with version control maintained throughout the project lifecycle.

AI-Powered Quoting Engine
Validated CAD files enter our proprietary AI quoting system, trained on 15+ years of shop floor data across 50,000+ steel fabrication projects. The algorithm analyzes part geometry, material requirements (ASTM A36, 4140, etc.), batch size, and machine-specific parameters to generate a preliminary quote within 90 minutes. Key outputs include:
Cost breakdown (material, machining, finishing)
Estimated lead time (standard or expedited)
Initial feasibility flags (e.g., thin-wall risks, tolerance conflicts)
The AI model continuously refines its accuracy using post-production cost variance data, maintaining a 95%+ quote accuracy rate for standard geometries.

Engineering Review and DFM Optimization
All quotes undergo mandatory Design for Manufacturability (DFM) review by our Senior Manufacturing Engineering team. This phase identifies and resolves potential production issues before machining begins:
Tolerance Analysis: Verifying GD&T callouts against CNC machine capabilities (±0.005″ standard; ±0.001″ achievable with metrology validation)
Material Utilization: Optimizing nest layouts to minimize waste (typical steel yield: 85–92%)
Process Sequencing: Determining optimal toolpaths, fixturing, and secondary operations (e.g., deburring, heat treatment)
Risk Mitigation: Flagging features requiring specialized tooling (e.g., internal radii <0.030″) or alternative processes (e.g., laser for >1″ plate)
Client collaboration is required for DFM recommendations, with revised quotes issued within 4 business hours post-review.

Production Execution
Approved designs move to production in Honyo’s climate-controlled facility, featuring:
Machine Fleet: HAAS VF-3 SS vertical mills (3-axis), DMG MORI CTX beta 1250 (5-axis), and Trumpf TruLaser 3030 (for sheet steel)
Material Verification: Incoming steel certified via MTRs (Mill Test Reports) and batch-tracked; hardness testing per ASTM E18 for alloy steels
In-Process QA: First-article inspection (FAI) per AS9102, with CMM checks at critical stages (e.g., pre/post-heat treatment)
Traceability: Real-time production tracking via barcode system, with digital work instructions synced to each machine

Quality-Controlled Delivery
Final inspection occurs against the original CAD model and client specifications:
| Checkpoint | Standard Protocol | Documentation |
|———————–|———————————————–|———————————–|
| Dimensional Accuracy | CMM scan of critical features (100% coverage) | FAIR (First Article Inspection Report) |
| Surface Finish | Ra measurement per ISO 1302 | Surface Roughness Certificate |
| Material Compliance | Cross-referenced MTRs + batch verification | Material Traceability Report |
| Packaging | VCI paper + custom crating for corrosion prevention | Packing List with Handling Instructions |
Certified parts ship via DHL/FedEx with real-time tracking. Standard lead time is 7–12 business days from DFM approval; expedited options (48–72hr) include overtime labor and priority scheduling. All deliveries include full quality documentation accessible via client portal.

This integrated workflow ensures Honyo Prototype delivers CNC-cut steel components that meet aerospace, medical, and industrial specifications while minimizing time-to-part and total project risk. Clients receive proactive updates at each phase transition through our dedicated project management interface.
