On a CNC rotary-draw bending machine, the linear axis along which the collet “transports” the tube to locate the bend at the line of tangency. The related rotary axis, which orients the tube to the plane of bend, is the B-axis.

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.
