From CAD to Part: The Process

Honyo Prototype San Diego CNC Workflow Overview
Honyo Prototype executes CNC machining operations for the San Diego region through a standardized, technology-driven workflow designed for precision, speed, and transparency. While our San Diego facility leverages local logistics advantages, the core process adheres to Honyo’s global engineering standards. Below is the end-to-end sequence:
Upload CAD
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid, or native SOLIDWORKS) via Honyo’s secure customer portal. The system validates file integrity and geometric complexity, confirming compatibility with San Diego facility capabilities including 3-axis, 5-axis, and mill-turn machining centers. All data is encrypted per ISO 27001 protocols, with immediate email confirmation upon successful upload.
AI-Powered Quoting Engine
Uploaded geometry triggers Honyo’s proprietary AI quoting system, which analyzes part topology, material requirements, tolerances, and surface finishes against real-time San Diego shop floor data. The algorithm cross-references machine availability, tooling libraries, and material stock levels at our San Diego hub to generate a binding quote within 2 business hours. Typical accuracy exceeds 95% against final production costs due to dynamic calibration with historical San Diego production metrics. Key quoting parameters include:
| Parameter | San Diego Facility Specification |
|---|---|
| Material Options | Aluminum 6061/7075, Stainless 303/316, Titanium, Plastics (Delrin, Nylon) |
| Tolerance Range | ±0.0002″ (精密级) to ±0.005″ (标准级) |
| Max Work Envelope | 5-axis: 38″ x 20″ x 20″; 3-axis: 40″ x 20″ x 20″ |
| Typical Quote Time | <2 business hours (95% of standard jobs) |
DFM Analysis and Engineering Collaboration
Upon quote acceptance, Honyo’s San Diego-based manufacturing engineers conduct a formal Design for Manufacturability review. This phase identifies potential cost drivers or risks such as thin-wall instability, non-optimal tool access, or tolerance stack-ups. Clients receive a detailed DFM report with actionable recommendations—presented via annotated CAD markups and cost-impact analysis—within 24 hours. Critical revisions are resolved through direct engineering calls with Honyo’s San Diego team, ensuring alignment before toolpath generation. No production proceeds without client sign-off on final DFM adjustments.
Production Execution
Approved designs move to the San Diego production floor where CNC programs undergo rigorous simulation in VERICUT to prevent collisions and verify G-code accuracy. Machining occurs on calibrated Haas and DMG MORI equipment with in-process CMM checks for critical features. San Diego operations maintain AS9100 and ISO 9001:2015 compliance, with full material traceability (including certs for aerospace-grade alloys) and real-time production tracking accessible via the client portal. High-mix, low-volume prototyping and bridge production runs are prioritized to meet aggressive timelines.
Delivery and Logistics
Finished parts undergo final inspection per ASME Y14.5 standards with a comprehensive FAI report. San Diego-based shipments leverage regional carriers for same-day dispatch within Southern California, with nationwide deliveries via FedEx Priority Overnight. Clients receive automated shipping notifications with tracking and digital documentation packages. Honyo guarantees on-time delivery for 98% of San Diego-originated orders, with expedited options available for urgent requirements. All parts include tamper-evident packaging and serialized traceability tags for end-use compliance.
This integrated workflow ensures San Diego clients receive aerospace-grade CNC machining with rapid turnaround, eliminating traditional quoting ambiguities and production delays through Honyo’s closed-loop digital infrastructure.
