SHEET

Bending

Bending forms sheet components around material, thickness, bend direction and tooling access.

ENGINEERING DOSSIER

Carry bend intent from the flat pattern into the inspected formed part

Flat-to-formed intent

Show material and thickness, bend direction, radii and which dimensions apply after forming.

Features near bends

Review holes, slots, tabs and reliefs against deformation, tooling access and the intended formed datum.

Sequence and tool access

Multiple bends can block later operations; identify which faces and hardware must remain accessible.

Accept the formed state

Inspect angles, flange relationships, datums and assembly interfaces on the part in its useful condition.

MANUFACTURING ROUTE

Route logic for Bending

Bending converts a released flat pattern through a planned press-brake sequence. Material condition, grain direction, tooling, bend order and springback compensation must be resolved together.

Define inside radius, bend angle, flange length, reliefs, hole-to-bend distance, grain direction and tool access without treating the flat pattern as the finished part.

DECISION QUESTIONS

Bending route and release questions

What must be defined before reviewing Bending?

Show material and thickness, bend direction, radii and which dimensions apply after forming. Review holes, slots, tabs and reliefs against deformation, tooling access and the intended formed datum.

Which interfaces need project-specific confirmation?

Multiple bends can block later operations; identify which faces and hardware must remain accessible. Escalate Sequence, springback and access and any geometry, access, material or interface requirement that the drawing does not resolve.

What should accompany release?

Inspect angles, flange relationships, datums and assembly interfaces on the part in its useful condition. Formed geometry and assembly fit

PROJECT BRIEF

Bending project brief and release checklist

Use these page-specific checks to turn the Bending route into reviewable CAD, drawing and inspection inputs.

Geometry and route input — Flat-to-formed intent

Show material and thickness, bend direction, radii and which dimensions apply after forming. Include the relevant CAD orientation, interfaces and quantity in the review brief.

Release evidence — Features near bends

Review holes, slots, tabs and reliefs against deformation, tooling access and the intended formed datum. Name the drawing dimensions and inspection evidence required at release.

RFQ handoff — Sequence and tool access

Multiple bends can block later operations; identify which faces and hardware must remain accessible. Upload controlled CAD/drawing inputs and state the unresolved route decision.
