Note: Tight tolerances require:
– Temperature-controlled environment (20°C ±0.5°C)
– Vibration-isolated machine tables

– Post-machining processes (e.g., grinding, lapping) for ±0.00005″ tolerances.
4. Material Specifications
| Material | Typical Grades | Machining Parameters | Tolerance Notes | Surface Finish Notes |
|———–|————————-|————————————————————————————–|———————————————————————————|——————————————|
| Aluminum | 6061-T6, 7075-T6, 2024-T3 | Speed: 800–1,500 SFM; Feed: 0.002–0.008″/tooth; Coolant: Air or minimal quantity (MQL) | Standard: ±0.0005″; Precision: ±0.0002″ (due to thermal expansion) | Ra 0.8 µm (32 µin) standard; anodizing-ready |

Critical Notes for Plastics (ABS/Nylon):
– Moisture Control: ABS/Nylon must be dried per ISO 1110 standards to prevent dimensional drift.
– Thermal Sensitivity: Chips must be removed immediately to avoid heat buildup (melting).
– Stress Relief: Annealing at 100–120°C for 1–2 hours is recommended for tight-tolerance parts.
5. Key Quality Controls
- In-Process Inspection: Laser profilometers, in-machine probing (e.g., Renishaw).
- Final Inspection: CMM (Zeiss ACCURA), optical scanners, surface roughness testers.
- Certifications: ISO 9001:2015, AS9100D (for aerospace), ISO 13485 (medical).
- Documentation: Full GD&T reports, material certs (e.g., Mill Test Reports for metals), and first-article inspection (FAI) per AS9102.
Recommendation for Clients
“To achieve optimal results, share your 3D CAD model (STEP, IGES) with critical dimensions highlighted. For tight tolerances (<±0.0002″), include details on material conditions (e.g., heat-treated state), functional requirements, and environmental exposure. We’ll provide a tailored process plan within 24 hours.”

Precision machining for mission-critical applications – where tolerances matter.
From CAD to Part: The Process
Honyo Prototype – kc precision machining workflow
(turn-around target: 3–15 calendar days, ±0.01 mm tolerance class)
-
Upload CAD
• Portal accepts any neutral format (STEP, IGES, Parasolid, JT, 3D-PDF) plus native NX, Creo, Catia, SolidWorks, Inventor.
• Geometry engine auto-heals gaps, removes duplicate faces, rebuilds bad normals.
• Security: every file is hashed, encrypted at rest, and stored in an isolated AWS VPC; NDA is auto-generated if none on file. -
AI Quote (≤5 min)
• Feature-recognition AI extracts 214 machinable attributes (undercuts, thin walls, deep cavities, bore aspect ratio, thread forms, etc.).
• A second neural net matches the features to Honyo’s live shop-floor data: spindle hours, tool life, pallet queue, CMM load.
• Pricing algorithm adds material cost (bar stock or plate), coating, tolerances <±0.01 mm, 5-axis index time, inspection cycles, and logistics.
• Customer sees three price-speed tiers (Express, Standard, Economy) and can slider-adjust quantity or surface finish; updated quote re-renders instantly. -
DFM (Design-for-Manufacturing)
• A senior manufacturing engineer (that’s me) reviews the AI flag report: thin-wall vibration risk, tool reach >7×D, internal sharp corners, non-standard thread call-outs.
• We send an annotated 3D PDF + Gantt chart within 12 h. Typical suggestions:
– Add 0.3 mm corner radius to eliminate EDM.
– Change M2 × 0.4 to M2 × 0.45 so we can use stocked TiAlN thread mill.
– Split 260 mm long part into two blanks to fit 3-axis travel and laser-weld later.
• Customer approves or iterates; change order is re-quoted by AI in minutes. -
