Technical Capabilities

Double cut sheet metal refers to a manufacturing process where a sheet metal part undergoes two distinct cutting operations, typically to achieve higher precision, complex geometries, or to separate nested components. This process is commonly performed using laser cutting, followed by secondary operations such as bending and welding to form complete assemblies. Below are the technical specifications related to laser cutting, bending, and welding for common materials used in double cut sheet metal fabrication, including Aluminum, Steel, ABS, and Nylon.

Parameter	Aluminum (e.g., 5052, 6061)	Steel (e.g., Mild Steel, 304 SS)	ABS (Acrylonitrile Butadiene Styrene)	Nylon (Polyamide)
Laser Cutting
Recommended Laser Type	Fiber laser	Fiber or CO₂ laser	CO₂ laser	CO₂ laser
Typical Thickness Range	0.5 – 6.0 mm	0.5 – 10.0 mm	1.0 – 5.0 mm	1.0 – 4.0 mm
Cut Tolerance	±0.1 mm	±0.1 mm	±0.2 mm	±0.2 mm
Edge Quality	Smooth, minimal dross	Smooth, slight oxidation on carbon steel	Clean, slight melting at edges	Slight melting; may require post-process
Bending
Bend Radius (Min)	1 × material thickness	1 × material thickness (carbon steel)	1.5 × material thickness	2 × material thickness
Springback Consideration	Moderate (varies by alloy)	Low to moderate	High	High
Tooling Requirement	Precision press brake with V-dies	Standard press brake	Low-tonnage brake; soft tooling	Low-tonnage brake; soft tooling
Welding
Suitable Methods	TIG, MIG, Laser Welding	MIG, TIG, Spot Welding, Laser	Not weldable via traditional methods	Ultrasonic, Vibration, Hot Plate
Joining Alternative	Mechanical fasteners, adhesives	Welding standard	Adhesives, snap fits	Adhesives, mechanical interlocks
Heat Sensitivity	Moderate (risk of warping)	High heat input tolerated (steel)	High (melts/deforms easily)	High (creep and thermal expansion)
General Notes	Non-ferrous, lightweight, corrosion resistant	Durable, magnetic (carbon steel), weldable	Thermoplastic; used for enclosures, not structural	High wear resistance; used in moving parts

Notes:
Double cut processes often involve a first cut to separate the blank, followed by bending and a second cut to remove support tabs or achieve final feature accuracy.
Aluminum and steel are primary candidates for integrated laser cutting, bending, and welding workflows.
ABS and nylon are non-metallic materials typically used in hybrid assemblies; they are generally not bent like sheet metal and require specialized joining techniques.
Thermal management is critical during laser cutting and welding to avoid distortion, especially in thin sheets and thermoplastics.

From CAD to Part: The Process

Honyo Prototype’s double cut sheet metal process refers to manufacturing operations where a single sheet undergoes two distinct cutting sequences to produce nested or interdependent parts. This is commonly required for complex assemblies, shared tooling features, or parts needing secondary operations before final separation. Our structured workflow ensures precision and efficiency:

CAD File Upload and Initial Processing
Customers submit detailed CAD files (DXF, DWG, or native formats) via our secure portal. Our system performs an immediate validation check for file integrity, unit consistency, and geometric completeness. For double cut scenarios, the system specifically identifies potential nesting conflicts, shared cut lines, and required sequencing based on layer assignments or feature annotations within the CAD model. This initial scan prevents downstream errors related to part interdependence.

AI-Powered Quoting Engine
Our proprietary AI quotation system analyzes the validated CAD data, applying real-time cost algorithms for double cut operations. The engine factors in material utilization efficiency across both cut sequences, kerf compensation between nested parts, secondary operation time for intermediate handling, and potential scrap reduction from optimized nesting. The generated quote includes a visual simulation of the double cut layout, highlighting the separation between primary and secondary cut phases, along with a detailed cost breakdown showing value engineering opportunities specific to the nested configuration.

Engineering-Driven DFM Analysis
Honyo’s manufacturing engineers conduct a rigorous Design for Manufacturability review focused on double cut feasibility. This phase addresses critical interdependencies that automated systems cannot resolve, such as:

DFM Check Category	Double Cut Specific Considerations
Geometric Integrity	Minimum bridge/tab dimensions between nested parts, kerf accumulation tolerance stack-up across both cuts
Process Sequencing	Optimal order of primary/secondary cuts to prevent part shift, required registration features for repositioning
Material Handling	Risk of part deformation during intermediate handling, support structure requirements for fragile nested arrays
Tolerance Stack-Up	Cumulative positional errors between cut phases, flatness control after first separation

The DFM report provides actionable recommendations, including suggested tab placements for part retention during the first cut, adjusted kerf values for shared edges, and potential design modifications to eliminate fragile geometries prone to distortion during the dual-operation cycle. Customers receive an interactive 3D DFM markup for collaborative resolution.

Precision Production Execution
Double cut production occurs on our fiber laser systems with automated material handling. The first cut sequence processes all primary contours and internal features while retaining parts via strategically placed micro-tabs. An automated shuttle system transfers the sheet to a secondary station where tabs are severed in the second cut phase, often using a different nozzle or power setting for clean separation. Throughout both stages, our MES tracks each nested part individually using barcode-linked work orders to prevent mix-ups. Real-time monitoring ensures kerf width consistency between operations, with automatic compensation applied if material thermal conditions change.

Quality-Controlled Delivery
All double cut parts undergo nested-array dimensional verification using coordinate measuring machines (CMM) that validate positional accuracy relative to shared edges. We package nested assemblies either as pre-separated units with protective interleaving or as fully assembled arrays based on customer assembly line requirements. Final delivery includes a nest layout map correlating part IDs to their position in both cut phases, along with first-article inspection reports documenting critical inter-part dimensions affected by the dual-operation process. Typical lead time for double cut projects remains 3-5 business days from DFM sign-off, with expedited options available for qualified geometries.
