Wiping (Metalworking)

In wiping, the longest end of the sheet is clamped, then the tool moves up and down, bending the sheet around the bend profile. Though faster than folding, wiping has a higher risk of producing scratches or otherwise damaging the sheet, because the tool is moving over the sheet surface. The risk increases if sharp angles are being produced. Wiping on press brakes.

This method will typically bottom or coin the material to set the edge to help overcome spring-back. In this bending method, the radius of the bottom die determines the final bending radius.Manual setup.
