Notes on Tight Tolerance Machining:
Achieving tolerances tighter than ±0.005 mm requires thermal stability, high-precision spindles (≤ 2 µm runout), and calibrated tool length compensation.
In-process probing and post-process CMM inspection are standard for verifying tight tolerance features.
Material stability (especially in Nylon and ABS) must be considered due to hygroscopic and thermal expansion characteristics.
At Honyo Prototype, advanced CAD/CAM workflows are integrated with high-rigidity CNC platforms to ensure repeatability and precision across all axis configurations and material types.
From CAD to Part: The Process
Honyo Prototype executes a streamlined CNC CAD/CAM workflow designed for precision, efficiency, and manufacturability, directly integrating engineering validation with production execution. Our process begins when a client uploads their native or neutral CAD file (STEP, IGES, Parasolid, SolidWorks, etc.) to our secure customer portal. This upload triggers immediate automated validation checks for file integrity, unit consistency, and geometric completeness, ensuring the dataset is production-ready before proceeding.
The validated CAD model enters our proprietary AI-powered quoting engine. This system analyzes geometric complexity, material requirements, tolerance specifications, and feature density against real-time machine availability, tooling libraries, and shop floor scheduling data. Unlike basic volume-based quoting tools, our AI cross-references historical production data from identical or similar geometries, generating a technically accurate cost and lead time estimate within minutes, including explicit justification for any complex feature surcharges.
Following client acceptance of the quote, the CAD model undergoes comprehensive Design for Manufacturability (DFM) analysis performed by our senior manufacturing engineering team. This is not an automated pass/fail check but a collaborative engineering review focused on optimizing the design for CNC machining efficiency while maintaining functional requirements. Key DFM activities include:
Verification of wall thicknesses, hole depths, and internal radii against minimum tooling capabilities
Assessment of feature accessibility for standard and custom tooling configurations
Identification of opportunities to reduce setups through geometric simplification
Tolerance stack-up analysis for critical interfaces
Material utilization optimization suggestions
We provide detailed DFM feedback with specific, actionable recommendations via annotated 3D markups and a formal report, enabling rapid design iteration. The table below illustrates the impact of our DFM process compared to standard industry practices.
| DFM Aspect | Standard Industry Practice | Honyo Prototype Practice | Client Benefit |
|---|---|---|---|
| Feedback Turnaround | 2-5 business days | < 24 business hours | Accelerated time-to-prototype |
| Revision Cycle Reduction | Typically 2-3 iterations | 85% of jobs resolved in ≤ 1 iteration | Lower NRE costs, faster validation |
| Tolerance Validation | Basic GD&T check only | Functional stack-up analysis with simulation | Higher first-pass yield, reduced scrap |
| Material Optimization | Rarely addressed | Standard practice with cost/benefit analysis | Lower material costs, sustainable output |
Upon DFM sign-off, our CAM team generates optimized machine toolpaths using Mastercam and Siemens NX, leveraging the validated CAD model and DFM insights. We apply dynamic milling strategies, high-efficiency roughing, and precision finishing toolpaths tailored to the specific machine platform (DMG MORI, Haas, Makino) and material. All programs undergo rigorous virtual machine simulation within CAM software and offline verification using GIBBS CAM Verify to eliminate collisions and ensure G-code integrity prior to shop floor deployment.
Production occurs in our climate-controlled facility on calibrated CNC equipment with documented maintenance records. We implement in-process inspections at critical stages using calibrated CMMs, optical comparators, and surface roughness testers, with full traceability of materials, tooling, and inspection data linked to the job. Final inspection documentation includes First Article Inspection reports per AS9102 or client-specified formats, with all critical dimensions verified against the original CAD model.
Delivery encompasses secure packaging meeting IPC-1601 standards, shipment tracking with real-time updates, and immediate electronic delivery of comprehensive quality documentation including dimensional reports, material certifications, and post-processing validation. Every shipped part includes a unique traceability code linking to its complete digital manufacturing record within our QMS, ensuring full compliance for regulated industries. This integrated process guarantees technically accurate quoting, manufacturable designs, and consistently high-quality CNC machined components delivered on schedule.
