What Is Sheet Metal Bending?

Sheet metal bending is a manufacturing process that forms flat metal sheets into angles, channels, boxes and other three-dimensional shapes using controlled force.

CNC press brakes are commonly used because they allow bending parameters, tooling and bend sequences to be controlled according to the part drawing.

Typical applications include:

• Brackets and mounting parts

• Electrical enclosures

• Machine covers and guards

• Control panels

• Frames and channels

• Industrial equipment components

• Custom OEM parts

For many products, bending is combined with laser cutting and welding to create a finished fabricated component.

CNC Press Brake Bending for Custom Parts

The bending process begins with the approved drawing and material specification.

ATT Machine reviews the part geometry, bend locations, material thickness, bend radius and required tolerances before production.

The typical workflow is:

Drawing Review → Flat Pattern → Cutting → Deburring → CNC Bending → Inspection → Secondary Fabrication → Packaging

For complex components, the bending sequence is planned to minimize tool interference and dimensional variation.

Materials for Sheet Metal Bending

Stainless Steel

Stainless steel is commonly used for industrial equipment, enclosures, food-processing equipment and applications requiring corrosion resistance.

Common grades include 304 and 316, depending on project requirements.

Carbon and Mild Steel

Carbon steel is widely used for machine frames, brackets, panels, guards and structural components.

Aluminum

Aluminum is useful when low weight and corrosion resistance are important.

Common alloys used in fabricated components include 5052 and 6061. The suitable alloy, bend radius and forming method depend on the final application.

Other Metals

Depending on the project, ATT Machine can review requirements for materials such as galvanized steel, brass and copper.

Material grade should always be specified on the drawing or RFQ because different grades can behave differently during bending.

Sheet Metal Bending Tolerances and Design

Bending accuracy is affected by more than the CNC machine.

Material properties, thickness, bend length, tooling, springback and part geometry can all influence the final result.

Bend Angle

The required bend angle should be clearly identified on the technical drawing, especially for parts with assembly or functional requirements.

Bend Radius

The inside bend radius should be selected according to the material and thickness.

A radius that is too small can increase the risk of cracking or deformation.

Bend Allowance and K-Factor

When a sheet is bent, the material stretches and compresses around the bend.

Bend allowance and K-factor are therefore important when developing the flat pattern for a finished part.

Hole-to-Bend Distance

Holes and slots positioned too close to a bend may deform during forming.

The distance should be reviewed together with material thickness, tooling and bend radius.

Bend Relief

Bend relief can help prevent tearing and deformation where a bend terminates near an edge or corner.

Multi-Bend Parts

Parts with several bends require careful bend sequencing.

The sequence should consider tool access, part orientation and interference between the component and the press brake tooling.

Design for Manufacturability (DFM) Review

A good sheet metal part should be designed not only to meet its function but also to be practical to manufacture.

Before production, ATT Machine can review:

• Material and thickness

• Bend radius

• Bend sequence

• Hole and slot locations

• Tool access

• Part geometry

• Required tolerances

• Potential forming issues

This early review can help identify manufacturing problems before production begins.

Recommended File Formats

For quotation and engineering review, customers can provide:

• STEP / STP

• DXF

• DWG

• PDF

• IGES

For the most accurate quotation, include the material grade, thickness, quantity and critical tolerances.

From Laser Cutting to Finished Bent Parts

Many sheet metal components begin as a flat laser-cut blank.

ATT Machine can coordinate multiple fabrication processes according to project requirements:

1. Laser Cutting

The flat pattern, holes, slots and cutouts are produced from the approved drawing.

2. Deburring

Sharp edges and cutting burrs are removed where required.

3. CNC Bending

The flat blank is formed into the required three-dimensional geometry.

4. Welding

Separate bent components can be welded when the final assembly requires it.

5. Surface Finishing

Finishing processes can be added according to the application and customer specification.

6. Quality Inspection

Finished parts are checked against the applicable drawing and quality requirements.

This integrated workflow can reduce the need to coordinate several suppliers for a custom fabricated component.

Quality Control for Sheet Metal Bending

Quality control should be based on the actual requirements of the part rather than a generic accuracy claim.

ATT Machine's inspection process can include checks for:

• Overall dimensions

• Bend angles

• Hole locations

• Part geometry

• Surface condition

• Material requirements

For OEM production, critical dimensions and inspection requirements should be identified during quotation and drawing review.

Where required by the project, customers can discuss applicable inspection and material documentation before production.
