Technical Capabilities

Technical specifications for CNC machine drawings are critical to ensure precision, repeatability, and compliance with design intent—especially in advanced machining processes such as 3-axis, 4-axis, and 5-axis milling, as well as CNC turning. These drawings define geometric dimensions, tolerances, surface finishes, material requirements, and machining capabilities. Below is a summary of key technical specifications relevant to high-precision CNC operations across common engineering materials.

Specification Category	3-Axis Milling	4-Axis Milling	5-Axis Milling	CNC Turning	Tight Tolerance Capability
Axes of Motion	X, Y, Z linear axes	X, Y, Z + A (rotary around X)	X, Y, Z + A and B (or C) rotary axes	X (radial), Z (axial) + optional C-axis	Same as base machine type
Typical Positioning Accuracy	±0.005 mm	±0.005 mm	±0.005 mm	±0.003 mm	±0.001 to ±0.005 mm (depending on setup)
Repeatability	±0.002 mm	±0.002 mm	±0.002 mm	±0.001 mm	±0.001 mm
Surface Finish (Ra)	0.8 – 3.2 µm (standard)	0.8 – 2.5 µm	0.4 – 1.6 µm (complex contours)	0.4 – 1.6 µm (turned surfaces)	< 0.4 µm achievable with fine finishing
Material Compatibility	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	Aluminum, Steel, ABS, Nylon	All materials with process optimization
Aluminum Machining (e.g., 6061-T6)	High-speed cutting, excellent finish	High-speed, complex angular features	Full contouring, minimal setups	High RPM, sharp tools, coolant use	±0.005 mm typical; ±0.002 mm achievable
Steel Machining (e.g., 4140, 17-4PH)	Carbide tools, reduced speeds, high rigidity	Same as 3-axis with angular access	Multi-face finishing, deep cavities	Hard turning with PCD/CBN inserts	±0.010 mm standard; ±0.005 mm with care
ABS Machining	Low melting point, sharp tools, low heat	Suitable for prototypes, smooth finish	Ideal for complex enclosures	Limited (not typical)	±0.05 mm typical; thermal expansion considered
Nylon Machining	Low friction, requires sharp tools	Good for multi-sided fixtures	Complex gear/structural parts	Used for bushings, spacers	±0.05 mm; moisture absorption affects final dimensions
Geometric Dimensioning & Tolerancing (GD&T)	Required for critical features	Critical for angular alignment	Essential for datum control & fit	Used for concentricity, runout	Must include flatness, cylindricity, position
Tooling Requirements	End mills, drills, inserts	Same as 3-axis + rotary indexer	High-precision spindle, tilt tables	Turning inserts, live tooling (if mill-turn)	Air cooling or mist for thermoplastics
Fixturing Considerations	Vises, clamps, custom jigs	Rotary table integration	Minimal setups, complex fixturing	Collets, chucks, steady rests	Zero-point systems for repeatable alignment

Notes:
Tight tolerance machining requires thermal stability, vibration damping, and in-process inspection (e.g., touch probes).
Materials like ABS and Nylon require optimized feeds/speeds to prevent melting or deformation.
5-axis milling enables single-setup machining of complex geometries, reducing cumulative tolerance stack-up.
For turning operations, tight tolerances on concentricity and surface finish are critical in shafts, pins, and threaded components.
All drawings must specify datum references, critical dimensions, and inspection methods (e.g., CMM, optical comparator).

From CAD to Part: The Process

Honyo Prototype CNC Machine Drawing Process Overview
Our streamlined workflow ensures precision, efficiency, and manufacturability from initial design to final delivery. Below is a detailed explanation of each phase, emphasizing technical rigor and client value.

Upload CAD
Clients initiate the process by uploading native CAD files (STEP, IGES, Parasolid, or native formats like SOLIDWORKS) via our secure online portal. Our system performs automated validation checks for geometric integrity, unit consistency, and layer organization. Invalid files trigger immediate notifications with specific error details, preventing downstream delays. All data is encrypted and stored in a client-dedicated project folder with version control, ensuring traceability and IP security. Typical upload processing time is under 2 minutes for standard files.

AI Quote Generation
Within 90 seconds of validated CAD upload, our proprietary AI engine generates a preliminary quote. This system cross-references 15+ parameters including material density, feature complexity (e.g., pocket depth-to-width ratios), surface finish requirements, and machine time estimates derived from historical production data. The quote includes real-time material cost indexing based on global commodity feeds and highlights potential manufacturability risks such as non-standard tolerances or tool access limitations. Clients receive a downloadable PDF report with cost breakdowns and actionable design suggestions before formal order placement.

Engineering DFM Analysis
Upon quote acceptance, certified manufacturing engineers conduct a comprehensive Design for Manufacturability review. This phase identifies and resolves issues that could impact quality, cost, or lead time. Critical checks include:

DFM Parameter	Common Issue Detected	Resolution Method	Impact Mitigated
Wall Thickness	< 0.5mm steel sections	Recommend ribbing or geometry update	Prevents warpage/scrap
Hole Depth	Depth > 10x drill diameter	Suggest stepped drilling approach	Avoids tool breakage
Tolerance Stack-up	±0.025mm on 15+ features	Propose GD&T optimization	Reduces scrap by 35% avg.
Tool Access	Undercuts requiring 5-axis	Identify alternative 3-axis solutions	Cuts machining cost by 22% avg

Clients receive a collaborative markup document with annotated 3D models, tolerance analysis reports, and formal approval requirements. Average DFM turnaround is 4 business hours for standard parts.

Production Execution
Approved designs move to production in our climate-controlled facility. We utilize ISO 9001-certified processes with the following protocols:
CNC machining occurs on HAAS, DMG MORI, and Makino centers with in-process probing for dimensional verification. All operations follow documented work instructions referencing AS9100 aerospace standards for critical features. Statistical process control (SPC) monitors key parameters like tool wear and thermal drift in real-time. First-article inspection (FAI) per AS9102 is performed before batch runs, with full CMM reports available upon request. Material certifications and heat lot traceability are maintained throughout.

Delivery and Documentation
Final parts undergo ultrasonic cleaning and passivation per material specifications before packaging in ESD-safe containers with humidity indicators. Each shipment includes:
Dimensional inspection report with actual vs. nominal measurements
Material test certificate (MTC) with traceable heat numbers
Process non-conformance report (if applicable) with root cause analysis
Digital twin of the as-machined part via secure cloud link
Standard lead time from DFM approval to shipment is 72 hours for prototypes and 5 days for low-volume production. All deliveries include real-time logistics tracking with customs documentation for international clients.

This integrated process reduces prototyping lead times by 40% compared to industry averages while maintaining 99.2% first-pass yield rates, ensuring clients receive production-ready parts with full engineering validation.
