Technical Capabilities

cnc block

CNC block machining involves precision material removal using computer-controlled tools to produce complex geometries with high accuracy. Honyo Prototype specializes in multi-axis CNC milling (3, 4, and 5-axis) and CNC turning for tight-tolerance components across a range of engineering materials including Aluminum, Steel, ABS, and Nylon. Our advanced machining capabilities support both prototyping and low-to-mid volume production with tolerances down to ±0.002 mm (±0.0001″) depending on geometry and material.

All CNC block operations are supported by in-process inspection (CMM, laser probing) and first-article inspection reports (FAIR) upon request. We ensure full traceability, material certifications, and adherence to ISO 2768 and customer-specific GD&T standards.


From CAD to Part: The Process

cnc block

Honyo Prototype’s CNC block manufacturing process delivers precision-machined components from digital design to physical part through a rigorously controlled workflow designed for speed, accuracy, and manufacturability. This process specifically addresses the production of parts machined from solid billet stock (blocks) using 3-, 4-, or 5-axis CNC milling and turning centers. Below is the detailed technical workflow.

CAD File Upload and Validation
The process initiates when the client uploads a native or neutral CAD file (STEP, IGES, Parasolid, or native formats including SolidWorks, Creo, NX) via Honyo’s secure customer portal. Our system performs immediate automated validation checks for geometry integrity, unit consistency, and file completeness. Files failing validation trigger a specific error report to the client, preventing downstream delays. Validated files proceed directly into the quoting engine without manual intervention.

AI-Powered Instant Quoting and Manufacturability Assessment
Honyo’s proprietary AI engine analyzes the validated CAD geometry in conjunction with material selection, quantity, and specified tolerances. This system calculates machine time, material utilization, fixture requirements, and secondary operations while simultaneously scoring manufacturability risks. The output is a comprehensive quote delivered within minutes, including: a firm price, estimated lead time, a DFM risk score (1-5, where 5 is high risk), and preliminary recommendations for potential geometry simplifications. Crucially, this AI stage identifies critical features requiring tight tolerance control or complex fixturing before human engineering review.

Engineer-Led DFM Analysis and Client Collaboration
All quotes undergo mandatory review by a Honyo Senior Manufacturing Engineer specializing in CNC block machining. The engineer validates the AI assessment, focusing on geometric complexity, tool access, wall thickness stability, and datum scheme feasibility. For parts scoring ≥3 on the DFM risk scale, the engineer generates specific, actionable recommendations—such as adjusting non-critical radii, modifying undercuts, or suggesting alternative stock sizes—to improve yield and reduce cost. These recommendations, alongside a detailed tolerance stack-up analysis for critical features, are presented to the client via the portal. Client approval or requested modifications must be formally acknowledged before production release, ensuring alignment on technical requirements.

CNC Production Execution
Upon client approval, the job enters production with strict adherence to Honyo’s documented procedures. Material certification (e.g., mill test reports for 6061-T6 aluminum or 304 stainless steel) is verified prior to cutting. Machining utilizes optimized, validated toolpaths generated in Mastercam or Siemens NX CAM, with in-process CMM verification at defined stages for features exceeding ±0.005″ tolerance. All blocks are machined on Haas, DMG MORI, or Makino equipment with real-time tool wear compensation. Secondary operations like deburring, heat treating (if specified), anodizing, or precision grinding are tracked via integrated MES, with full material and process traceability maintained.

Quality-Controlled Delivery and Documentation
Final inspection occurs against the approved drawing using calibrated CMMs, optical comparators, and surface roughness testers. A comprehensive inspection report (including FAI per AS9102 where applicable) and material certs are packaged with the shipment. Parts are vacuum-sealed with desiccant for moisture-sensitive materials and shipped via client-specified carriers with real-time tracking. Delivery includes digital access to all process documentation through the client portal, enabling full audit trail verification.

The following table summarizes typical throughput metrics for standard CNC block projects:

Process Stage Standard Block (≤ 150mm cube, Al 6061) Complex Block (Multi-axis, Tight Tolerances)
AI Quote Generation < 10 minutes < 15 minutes
DFM Engineer Review 4-8 business hours 12-24 business hours
Production Lead Time 3-5 business days 7-12 business days
Typical First-Pass Yield 98.5% 92.0%

This integrated process minimizes non-value-added time while ensuring engineering rigor at critical decision points. Honyo’s closed-loop system captures DFM feedback and production data to continuously refine the AI quoting engine, directly improving future manufacturability assessments for all clients.
