All CNC programs for tight tolerance work must include tool deflection compensation, thermal drift considerations, in-process probing routines (where available), and post-process CMM validation protocols. Material-specific tooling and feeds are critical to maintaining dimensional accuracy and surface integrity, especially when transitioning between metals and engineering plastics.

From CAD to Part: The Process

Honyo Prototype employs a streamlined, technology-driven workflow for CNC machining projects designed to maximize efficiency, reduce lead times, and ensure manufacturability from initial concept to final delivery. Our integrated process leverages proprietary AI systems and engineering expertise at critical decision points.

CAD Upload and Initial Processing
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid, or native formats like SolidWorks) via our secure customer portal. Our system performs an immediate validation check for file integrity, unit consistency, and geometric completeness. Invalid or incomplete submissions trigger an automated notification requesting correction, preventing downstream delays. Validated files proceed directly to the AI quotation engine without manual intervention.

AI-Powered Quotation Generation
Honyo’s proprietary AI engine analyzes the validated CAD geometry to generate an instant, data-driven quotation within minutes. This system evaluates over 200 parameters including part complexity, feature density, material requirements, required tolerances, and surface finish specifications. The AI cross-references real-time machine availability, historical production data from our CNC fleet (Haas, DMG MORI, Makino), and current material market pricing. Clients receive a detailed quote containing estimated lead time, cost breakdown by operation, and recommended material options. This eliminates traditional quotation bottlenecks while providing unprecedented transparency.

Engineering-Led DFM Analysis and Optimization
Following quote acceptance, our manufacturing engineering team conducts a rigorous Design for Manufacturability (DFM) review. This is not an automated step but a value-added engineering service where senior CNC programmers and process engineers collaborate with the client to optimize the design for production. Critical DFM checks include:

DFM Check Category	Specific Parameters Verified	Impact Mitigated
Geometric Feasibility	Minimum wall thickness, undercuts, internal radii	Prevents part failure during machining
Tool Access & Clearance	Tool reach requirements, collision risks	Eliminates non-productive machine stops
Tolerance Realism	GD&T feasibility, stacked tolerances	Avoids excessive inspection/scrap
Material Utilization	Stock size optimization, nesting efficiency	Reduces material waste by 15-30%
Secondary Operations	Deburring complexity, fixturing requirements	Minimizes post-CNC handling time

Engineers provide actionable feedback through our portal with annotated 3D models, suggesting design modifications that maintain functional intent while improving machinability. Client approval is required before programming commences, ensuring alignment.

CNC Programming and Production Execution
Upon DFM sign-off, our CAM programming team generates optimized toolpaths using Mastercam and Fusion 360. Programs undergo virtual machine simulation (Vericut) to verify collision avoidance and cycle time accuracy. Critical processes utilize in-process probing for first-article validation. Production occurs in our climate-controlled facility on certified equipment with documented SPC tracking for critical dimensions. All CNC operations follow AS9100-aligned procedures with real-time monitoring of spindle load, tool wear, and dimensional conformance via integrated sensors.

Finishing, Quality Control, and Delivery
Post-machining operations include precision deburring, bead blasting, or anodizing as specified. Each part undergoes CMM inspection against the original CAD model with full FAIR documentation. Final packaging uses custom-designed anti-static, shock-absorbing materials meeting IPC-1601 standards. We provide clients with real-time shipment tracking through our logistics partners (DHL, FedEx) and guarantee on-time delivery via our production scheduling system, which dynamically adjusts for machine utilization and priority workflows. All deliveries include comprehensive documentation: inspection reports, material certifications, and process validation records accessible via the client portal.
