A tangent located between two bends made on the same section of tubing. Compare end tangent; also see tangent. The mid-tangent becomes an important consideration in tool design and machine process if its length is shorter than the recommended clamp length for the tube-bending application. In those instances when a short mid-tangent compromises the optimal clamp design, a conflict arises between ease-of-bending and bend quality that often is not resolved unless compound clamps are used. See the entries under clamp die and compound clamp for a full treatment of this issue.

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.
