Material Compatibility	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	Aluminum, Steel (preferred), limited in ABS/Nylon
Aluminum (6061-T6) Notes	High material removal, excellent finish	Suitable for indexed angled features	Ideal for complex contours and undercuts	Fast turning, good chip control	±0.005 mm achievable with thermal control
Steel (1018) Notes	Moderate cutting speed, requires rigid setup	Requires high torque, slower feeds	Precision toolpath for hardened variants	Excellent for shafts, pins	±0.003 mm with ground finishing
ABS Notes	Low melting point, sharp tools required	Avoid excessive heat buildup	Shallow depths of cut recommended	Suitable for prototypes	±0.02 mm typical; tight tolerance limited by creep
Nylon (6/66) Notes	Gummy material, requires chip evacuation	Use air blast cooling	Avoid annealing through heat	Turning preferred over milling	±0.03 mm typical; hygroscopic swell affects tolerance
Applications	Flat parts, enclosures, jigs	Multi-sided parts with indexing	Aerospace, medical, complex geometries	Cylindrical parts, threads, shafts	Gauges, inserts, mating components

Notes on Tight Tolerance Machining:
Achieving tight tolerances (±0.005 mm or better) requires environmental control (stable temperature), precision metrology (CMM verification), high-end CNC machines with linear scales, and reduced machining allowances. Materials like Aluminum and Steel are preferred due to dimensional stability. Plastics such as ABS and Nylon are less suitable for tight tolerances due to moisture absorption, thermal expansion, and creep.

From CAD to Part: The Process

Honyo Prototype Machining Process Overview

Honyo Prototype employs a streamlined, technology-driven workflow for CNC machining projects, designed to minimize lead times while ensuring manufacturability and quality. The process begins when a customer uploads a CAD file to our secure portal. Accepted formats include STEP, IGES, Parasolid, and native CAD files from SolidWorks, Fusion 360, and Creo. Upon upload, our system performs an immediate geometry validation check to identify common issues such as non-manifold edges, missing surfaces, or unit inconsistencies. Files failing validation trigger an automated notification to the customer with specific error details, enabling rapid correction without engineer intervention.

AI-Powered Quoting Engine
Validated CAD files enter our proprietary AI quoting system, which analyzes geometric complexity, material requirements, tolerances, and surface finishes. The AI cross-references real-time data from our machine shop—including current workload, tooling availability, and material costs—to generate a preliminary quote within 15 minutes. This initial quote includes base pricing, estimated lead time, and high-risk manufacturability flags. Crucially, the AI output is never final; it undergoes mandatory review by a Honyo applications engineer who validates material selections, adjusts for secondary operations (e.g., tapping, deburring), and incorporates client-specific requirements like NADCAP or AS9100 compliance. This dual-layer approach ensures quotes are both rapid and technically rigorous.

Engineer-Led DFM Analysis
Following quote acceptance, our DFM phase begins with a dedicated manufacturing engineer conducting a comprehensive design review. Unlike automated-only DFM tools, our process combines algorithmic analysis with human expertise to identify cost drivers and risks. Key focus areas include: optimizing wall thicknesses to prevent chatter, verifying tolerance stack-ups against machine capabilities (±0.0002″ for critical features), suggesting alternative radii to reduce tool changes, and evaluating fixturing feasibility. We provide clients with a detailed DFM report listing actionable recommendations—such as consolidating features to eliminate setups—and collaborate iteratively via secure portal comments until all parties approve the final design. This phase typically reduces production costs by 18–35% by resolving issues before metal cutting begins.

Precision Production Execution
Approved designs move to production in our climate-controlled facility housing 42 CNC machines (18 3-axis, 20 5-axis, 4 Swiss-type lathes). Each job follows a standardized workflow: material certification verification, first-article inspection via CMM or optical comparator, in-process checks at critical stages (e.g., after roughing and semi-finishing), and final full-spectrum validation against the original CAD model. All machining parameters are monitored in real time through our MES system, with automatic alerts for tool wear deviations exceeding 5% of nominal values. Complex assemblies undergo additional functional testing, such as press-fit validation or fluid flow checks, per client specifications.

Quality-Controlled Delivery
Completed parts undergo a final QA gate where our inspectors verify conformance to all drawing requirements, including material certs, surface roughness reports, and dimensional data packages. Every shipment includes a digital quality dossier accessible via our client portal, containing inspection reports, process videos (upon request), and traceability logs linking each part to specific machine runs and operators. Parts are packaged using static-dissipative materials for electronics components or vapor-corrosion inhibitors for aerospace alloys, with shipping methods selected to balance speed and part sensitivity. Standard lead times from DFM approval to delivery are summarized below:

Part Complexity	Typical Lead Time	Includes
Simple (≤5 features, standard tolerances)	3–5 business days	First-article inspection, basic packaging
Moderate (multi-setup, tight tolerances ±0.001″)	7–10 business days	CMM report, custom fixtures, functional testing
Complex (5-axis, sub-assembly, critical surfaces)	12–18 business days	Full FAI per AS9102, material traceability, accelerated life testing

This integrated process ensures clients receive precision-machined parts with documented quality, predictable timelines, and zero surprise costs—turning design intent into physical reality with engineering integrity.
