From CAD to Part: The Process

Honyo Prototype Custom Precision Metal Machining Process Overview

Honyo Prototype delivers end-to-end custom precision metal machining through a structured, technology-driven workflow designed for speed, accuracy, and manufacturability. Our process begins with CAD upload and concludes with certified delivery, integrating AI and engineering expertise at critical stages to minimize risk and optimize outcomes. Below is a detailed technical breakdown of each phase.

Upload CAD
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid, or native formats from SolidWorks, Fusion 360, etc.) via our secure customer portal. Our system validates file integrity, checks for geometric completeness, and flags potential issues such as missing tolerances, non-manufacturable features, or unit inconsistencies. This step ensures the design foundation meets baseline requirements for precision machining, reducing downstream delays. All data is encrypted and handled under strict NDA protocols.

AI Quote Generation
Uploaded CAD data is processed through our proprietary SmartQuote AI engine, which performs rapid geometric analysis, material utilization forecasting, and machine time estimation. The AI cross-references real-time factors including material availability, shop floor capacity, and historical process data to generate a preliminary quote within 2–4 hours. This quote includes upfront cost breakdowns, lead time estimates, and preliminary feasibility flags. Crucially, the AI output is reviewed and validated by a dedicated manufacturing engineer to ensure accuracy—particularly for complex geometries or tight tolerances (±0.0005″ achievable)—before client submission.

DFM Analysis and Engineering Collaboration
Upon quote acceptance, our engineering team conducts a formal Design for Manufacturability (DFM) review. This is not a passive check but an iterative collaboration where our engineers provide actionable feedback to optimize the design for precision metal machining. Common DFM recommendations include adjusting wall thicknesses to prevent chatter, modifying internal radii for tool access, or suggesting alternative materials to reduce cost without compromising performance. Critical DFM considerations are summarized below.

DFM Focus Area	Common Issue Identified	Honyo Resolution Strategy
Geometric Complexity	Undercuts requiring 5-axis	Propose simplified features or justify 5-axis use
Tolerance Stack-Ups	Over-specified GD&T	Recommend relaxed tolerances on non-critical surfaces
Material Selection	Exotic alloys with long lead	Suggest equivalent domestic alternatives
Feature Accessibility	Deep cavities < 10:1 aspect	Redesign for progressive roughing/finishing

Clients receive a detailed DFM report with annotated CAD markups and cost-impact analysis. Revisions are incorporated via version-controlled portal updates, ensuring full traceability.

Production Execution
Approved designs move to our climate-controlled machining facility equipped with multi-axis CNC mills (3-axis to 5-axis), Swiss-type lathes, and wire EDM systems. All operations adhere to ISO 9001:2015 and AS9100 standards. Key production controls include:
First Article Inspection: Full CMM validation against CAD model before batch runs.
In-Process Gauging: Statistical process control (SPC) with real-time tool wear compensation.
Material Certification: Mill test reports and traceable material certs (e.g., AMS 4928 for Ti-6Al-4V).
Complex assemblies undergo in-house secondary operations including precision grinding, honing, and non-destructive testing (NDT) as required.

Delivery and Documentation
Final inspection generates a comprehensive quality package including CMM reports, surface roughness data, and material certifications. Parts are packaged in anti-corrosive VCI bags with custom foam cradling for transit-sensitive components. Delivery includes digital and physical documentation:
FAI reports per AS9102
Dimensional inspection certificates
RoHS/REACH compliance statements (if applicable)
Standard lead time from DFM sign-off to delivery is 10–15 business days for prototypes and 15–25 days for low-volume production. Expedited options (5–7 days) are available for critical-path projects.

This integrated workflow ensures Honyo Prototype achieves >95% first-pass yield on precision metal components while maintaining full transparency from design intent to certified delivery. Clients retain full visibility via our cloud-based project dashboard, which provides real-time updates on production milestones and quality metrics.
