Technical Capabilities

CNC machining is a subtractive manufacturing process that uses computer-controlled tools to remove material from a workpiece to produce precision components. The process is widely used for creating high-accuracy parts across industries such as aerospace, medical, automotive, and industrial equipment. Key configurations include 3-axis, 4-axis, and 5-axis milling, as well as CNC turning, each offering different degrees of rotational and linear movement for enhanced geometric capability.

Feature	3-Axis Milling	4-Axis Milling	5-Axis Milling	CNC Turning	Tight Tolerance Capability
Motion Axes	X, Y, Z linear axes	X, Y, Z + A (rotation around X)	X, Y, Z + A and B (or C) rotary axes	X (radial), Z (axial), with spindle rotation	N/A
Typical Use Case	Flat or planar geometry, simple features	Indexing around one rotary axis (e.g. drilling holes on sides)	Complex contours, organic shapes, deep cavities	Cylindrical parts (shafts, bushings, fittings)	Critical dimensions requiring ±0.001″ (±0.025 mm) or tighter
Max Work Envelope (Typical)	20″ x 40″ x 20″	20″ x 40″ x 20″ + rotary indexing	16″ x 30″ x 20″ with full continuous 5-axis	Diameter up to 16″, length up to 48″	Depends on machine and setup, typically up to 24″ in any axis
Surface Finish (Typical)	32–125 μin Ra	32–125 μin Ra	16–63 μin Ra (complex surfaces)	16–63 μin Ra (machined cylindrical)	As low as 8–16 μin Ra with fine finishing passes
Materials Compatible	Aluminum (6061, 7075), Steel (1018, 4140), ABS, Nylon	Same as 3-axis, with improved access for complex setups	Same, optimized for hard-to-reach features	Same, especially suited for bar stock forms	All materials, with enhanced stability for Aluminum and Steel
Aluminum Machinability	Excellent; high MRR, low tool wear	Good; indexing improves access	Excellent; reduced tool interference	Excellent; smooth finishes at high RPM	Achieves ±0.0005″ with proper fixturing and thermal control
Steel Machinability	Good; requires rigid setup and carbide tools	Moderate; longer cycle times	Moderate to good; benefits from tool tilt	Good; especially for case-hardened steels	±0.001″ typical, ±0.0002″ achievable with precision turning
ABS Machinability	Good; low melting point requires sharp tools and low heat	Good; vacuum fixturing recommended	Moderate; risk of chatter; shallow depths	Limited; rarely turned, more milled	±0.002″ typical due to thermal expansion
Nylon Machinability	Moderate; prone to deflection, requires sharp cutting	Moderate; clamping must avoid deformation	Moderate; best with cryogenic cooling	Good; for bushings, rollers, insulators	±0.0015″ achievable with stable setup and dry environment

Note: Tight tolerance performance is highly dependent on machine calibration, tooling quality, fixturing rigidity, environmental control (temperature, vibration), and operator expertise. 5-axis milling allows for single-setup machining of complex geometries, reducing cumulative tolerance stack-up. CNC turning is ideal for high-precision rotational parts, especially when combined with live tooling (mill-turn centers) for secondary milling operations.

From CAD to Part: The Process

Honyo Prototype implements a rigorously defined CNC machining workflow designed for precision, efficiency, and client transparency. This integrated process ensures manufacturability while minimizing time-to-part and reducing non-conformance risks. Below is the technical breakdown of each phase.

CAD Upload and Initial Processing
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid) via our secure customer portal. Our system performs immediate automated validation checks for file integrity, unit consistency, and geometric completeness. This step eliminates common upstream errors such as missing datums or inconsistent units before engineering review begins. All uploaded data is encrypted and stored in our ISO 27001-certified environment, ensuring IP protection throughout the project lifecycle.

AI-Powered Quoting Engine
Validated CAD models enter our proprietary AI quoting system, which analyzes geometric complexity, feature tolerances, material requirements, and surface finish specifications. The engine cross-references real-time data from our machine shop floor, including current capacity on HAAS and DMG MORI equipment, material pricing feeds from certified suppliers, and historical production metrics. Within 2 hours, clients receive a detailed quote specifying exact lead times, cost breakdowns by operation, and preliminary material recommendations. Crucially, the AI flags potential manufacturability concerns at this stage—such as thin walls below 0.5mm or deep cavities exceeding 10:1 aspect ratios—enabling early risk mitigation.

Engineering-Led DFM Analysis
All quotes undergo mandatory review by our in-house manufacturing engineering team. This phase extends beyond automated analysis to human expertise in geometric dimensioning and tolerancing (GD&T) optimization. Engineers perform:
Tolerance stack-up analysis against ISO 2768 medium accuracy standards
Toolpath simulation for hard-to-reach features
Material utilization optimization to reduce waste
Fixture strategy validation for 5-axis accessibility
Clients receive a formal DFM report with actionable recommendations, such as suggesting alternative radii for end mills or consolidating setups. Only after client approval of the DFM report does the project advance, ensuring alignment on technical feasibility.

Precision Production Execution
Approved jobs move to production with full traceability:
Material certification (e.g., EN AW-2024 T351 for aluminum) is verified upon receipt
First-article inspection (FAI) per AS9102 standards for critical features
In-process checks at predefined stages using calibrated CMMs and optical comparators
Real-time machine monitoring via MTConnect for spindle load, vibration, and thermal compensation
Our facility maintains ISO 9001:2015 and IATF 16949 certifications, with environmental controls holding temperatures at 20±1°C to minimize thermal drift during micron-level machining.

Quality-Controlled Delivery
Final inspection includes comprehensive dimensional validation against the original CAD model using Zeiss CONTURA CMMs, with full inspection reports available via client portal. Parts undergo visual inspection per ASTM E3022 for surface defects and are packaged with anti-corrosion VCI paper for shipment. Standard lead times by complexity are:

Complexity Tier	Features Included	Typical Lead Time
Standard	Tolerances ±0.1mm, basic geometries	5-7 business days
Medium	Tight tolerances (±0.025mm), multiple setups	8-12 business days
High	Micro-machining (<±0.01mm), complex 5-axis contours	13-20 business days

All deliveries include digital dossiers with inspection data, material certs, and process documentation. This closed-loop system ensures 99.2% on-time delivery performance while providing clients with auditable manufacturing evidence for regulated industries.
