Reliable curved sheet-metal bends, without manual intervention

meviy is improving how curved bends in sheet-metal parts are handled—making automatic quoting more reliable and reducing frustration during CAD upload. With this release, engineers can now take advantage of RR (Roll Radius) bending using dedicated R-bend tooling, while the platform automatically adjusts unsupported radii to manufacturable sizes.

 

This is a reliability upgrade designed to keep your digital workflow smooth: fewer quote failures, fewer manual requests, and more confidence in realistic sheet-metal designs.

What engineers struggle with

 

Curved sheet-metal bends have long been a pain point in automated quoting workflows. Prior to this release, engineers often faced:

 

  • Limited support for FR (feeding radius) bending on R-curved shapes
  • Unstable bending conditions for certain radii
  • Automatic quote failures that forced manual quote requests
  • Repeated error messages during CAD uploads
  • Time-consuming redesign cycles and frustration

 

The result? Engineers had to compromise on design, spend extra time requesting manual quotes, or adjust geometries to avoid errors, slowing iteration and increasing project friction.

What this release changes

 

With RR-bending and automated radius adjustment, meviy now handles curved bends more reliably:

 

  • Automatic detection of unstable R-bend sections: The system identifies inner radii that cannot be reliably processed with FR bending.
  • Automatic radius adjustment: Unsupported radii are rounded down to the nearest manufacturable R size, selected from predefined, supplier-supported values.
  • Dedicated R-bend tooling: Adjusted parts are produced accurately without additional manual intervention.
  • Automatic quote success: Automatic quotation now works for realistic curved geometries.
  • Transparent communication: The adjusted radius is clearly displayed in the viewer and on drawings, so engineers can accept it or review without modification.

 

This means engineers can upload curved sheet-metal designs with confidence, reducing redesigns and manual quote requests while keeping the CAD-first workflow intact.

How it works

 

  • Threshold for adjustment: When the inner radius is larger than 2× material thickness (2t) but unsuitable for FR bending, meviy converts it to the nearest supported R size.
  • Example for clarity (t = 1 mm):
    • Inner R ≈ 2.5 → converted to R1
    • Inner R ≈ 8 → converted to R6

 

Unsupported radii are automatically converted to the nearest manufacturable size, ensuring stable bending while preserving design intent.

Applications

Industrial Machinery and Automation

 

Control cabinets, frames, and enclosures often use large-radius bends for structural strength and cable routing. 

Electronics and Electrical Equipment

 

Housings, panels, and brackets need clean, consistent radii for fit, airflow, and assembly. Stable bending ensures predictable results without manual intervention.

Automotive and Mobility

 

Fixtures, brackets, covers, and low-volume components frequently include curved bends. Automatic radius adjustment avoids repeated redesign cycles during prototyping.

Energy and Infrastructure Equipment

 

Sheet-metal components in cabinets, supports, and protective housings benefit from fewer quoting delays and more consistent outcomes.

General OEM Manufacturing and SMEs

 

Engineering teams producing one-offs or small batches gain faster iteration without requiring deep bending expertise or workaround geometries.

Reliable quoting, less frustration

 

This release reinforces meviy as a platform that keeps the digital workflow moving, even for challenging sheet-metal geometries. By detecting unstable bends and automatically proposing manufacturable radii, meviy reduces automatic quotes failures and gives engineers the confidence to upload realistic R-curved designs directly.

 

The outcome: faster iteration, fewer redesign loops, and more predictable results—all without leaving your CAD-first workflow.

Frequently Asked Questions

What is RR bending?

 

RR (Roll Radius) bending uses dedicated R-bend tooling to produce consistent, curved sheet-metal bends. It is particularly useful when standard FR (feeding radius) bending cannot produce stable results.

How does meviy handle unsupported radii?

 

Unsupported inner radii are automatically converted to the nearest manufacturable R size, ensuring the part can be produced reliably. The adjusted radius is displayed in the viewer and on drawings.

Will the automatic quote still fail for curved bends?

 

With this release, automatic quote succeeds for most R-curved geometries. Manual quote (MQ) is only required when the geometry or material is outside the manufacturable range.

Does this work for all sheet-metal materials?

 

Yes. RR bending and automatic radius adjustment are compatible with standard sheet-metal materials supported on meviy, including mild steel, stainless steel, and aluminium alloys.
