Multi-setup complex components are supported with detailed process planning and first-article inspection (FAI) reporting per AS9102 or customer format.
From CAD to Part: The Process
Honyo Prototype delivers precision heavy machining services through a structured five-stage workflow optimized for large-scale, high-complexity components. This process ensures technical rigor while addressing the unique demands of heavy machining such as material integrity, thermal stability, and structural rigidity. Below is a detailed explanation of each phase.
CAD Upload and Validation
Clients initiate the process by uploading native CAD files (STEP, IGES, or native formats like SolidWorks) via Honyo’s secure portal. Our system performs immediate validation checks for geometric completeness, unit consistency, and file integrity. For heavy machining projects, we specifically verify model scale accuracy, material block dimensions, and draft angles critical for large-part manufacturability. Any discrepancies trigger automated notifications to the client for resolution prior to quotation.
AI-Powered Quotation
Honyo’s proprietary AI engine analyzes the validated CAD model to generate a technical and commercial quote within 4 business hours. The algorithm factors in heavy machining-specific variables: material density and waste ratios for large billets, machine time for deep cavity milling, specialized tooling requirements (e.g., anti-vibration tool holders), and thermal compensation strategies. Cost calculations incorporate scrap rate projections for high-value alloys like Inconel or titanium, with transparent breakdowns of material, machining, and finishing costs. Clients receive a downloadable PDF quote with technical assumptions clearly documented.
Engineering-Driven DFM Analysis
All quotes undergo mandatory Design for Manufacturing review by Honyo’s senior heavy machining engineers. This phase focuses on structural feasibility for large components, addressing:
Stress points during multi-ton part handling
Optimal fixture design to prevent deflection in thin-walled sections
Toolpath sequencing to minimize residual stresses in monolithic structures
Tolerance stack-up analysis for assemblies exceeding 2m in length
Key DFM considerations for heavy machining are summarized below:
| DFM Parameter | Heavy Machining Focus | Honyo’s Mitigation Approach |
|---|---|---|
| Material Removal Rate | Minimizing heat generation in deep cuts | Adaptive roughing with trochoidal toolpaths |
| Geometric Stability | Preventing distortion in large cast/forged blanks | Stress-relief cycle integration in process plan |
| Surface Integrity | Maintaining fatigue strength in critical zones | Controlled finish passes with polished tooling |
| Tolerance Control | Compensating for thermal drift in long cycles | In-process metrology with thermal sensors |
Engineers collaborate directly with clients to resolve conflicts, providing annotated CAD markups and alternative design solutions where necessary.
Precision Production Execution
Approved orders move to Honyo’s heavy machining facility equipped with 5-axis gantry mills (travel up to 10m x 4m x 2m), vertical turning lathes for diameters >3m, and robotic material handling. Production follows:
Rigorous first-article inspection per AS9102 standards
In-process checks at critical stages using Faro Arm CMMs
Real-time machine monitoring for vibration and thermal deviations
Dedicated project management with weekly technical updates including metrology reports
All processes adhere to ISO 9001 and NADCAP standards, with special attention to documentation for aerospace and energy sector compliance.
