A style of cut for the feathered edge of a wiper die, in which the radius face is substantially offset from its natural point of intersection with the tube cavity of the wiper. Also called aero-cut, aerospace cut, or aircraft cut. The purpose of offset geometry is to produce a feathered edge that can be set at zero-rake and withstand the forces of high-pressure bending.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
