From CAD to Part: The Process
CNC Precision Machined Parts: Production Process Workflow
Shenzhen Honyo Prototype delivers exceptional CNC machined components through a rigorously defined workflow designed to maximize precision, minimize lead times, and ensure manufacturability from the initial concept. Our integrated process seamlessly transitions from digital design to certified physical part, leveraging automation and expert engineering oversight at every critical stage. This structured approach guarantees consistent quality and cost-effectiveness for our clients’ most demanding applications.
The workflow commences with the AI-Powered Quoting System. Upon receipt of a valid 3D CAD model (STEP, IGES, or native formats preferred), our proprietary AI engine performs an immediate geometric and feature analysis. It automatically identifies critical dimensions, tolerances, material requirements, and complex geometries. This analysis feeds into our dynamic costing algorithm, which factors in machine time estimates based on feature complexity, material type and cost, required surface finishes, and necessary fixturing. The result is a highly accurate preliminary quote and lead time estimate delivered within two business hours, significantly accelerating the project initiation phase compared to manual quoting methods. This initial AI assessment also flags potential high-risk features requiring immediate engineering review.
Following client approval of the quote, the project enters the mandatory Design for Manufacturability (DFM) Review stage. Our experienced manufacturing engineers conduct a thorough technical assessment, moving beyond the AI’s initial scan to evaluate the design’s practical producibility on CNC equipment. This critical phase identifies potential issues such as inadequate tool access, problematic thin walls, excessive tolerances driving cost, suboptimal hole depths, or features requiring complex multi-axis setups or secondary operations. The DFM review aims to optimize the design for efficient machining while maintaining functional requirements, often suggesting minor, non-critical modifications that drastically reduce cost and lead time without compromising performance. Key DFM parameters we verify include:
| Parameter | Acceptable Range | Action Required if Outside Range |
| :—————– | :————————— | :————————————- |
| Minimum Hole Depth | ≤ 10x Diameter (Standard Drill) | Suggest deeper hole tolerance relaxation or alternative process |
| Wall Thickness | ≥ 0.8mm (Aluminum) / ≥ 1.2mm (Steel) | Recommend design modification or material change |
| Internal Corner Radius | ≥ 0.5mm (Standard End Mill) | Propose larger radius or T-bone feature |
| Surface Finish (Ra) | 0.8μm – 6.3μm (Machined) | Confirm requirement necessity; tighter finishes increase cost significantly |
Upon DFM sign-off by both Honyo engineering and the client, the project advances to CNC Production. Our CAM programming team generates optimized, collision-avoidant toolpaths using industry-leading software (Mastercam, Fusion 360). Each program undergoes rigorous virtual simulation to verify accuracy and safety. Certified machinists then set up the appropriate CNC center (3-axis, 4-axis, or 5-axis), utilizing precision vices, custom fixtures, or tombstones as required. Machining proceeds under strict process control, with in-process inspections verifying critical dimensions at defined stages. The final part undergoes comprehensive First Article Inspection (FAI) per AS9102 or client-specific requirements using calibrated CMMs, optical comparators, and surface roughness testers. All inspection data is documented and provided with the shipment, ensuring full traceability and adherence to the agreed specifications before delivery. This end-to-end controlled process is fundamental to Honyo Prototype’s reputation for reliable, high-precision CNC machining.
