A Cartesian coordinate system for specifying tubular components, especially automotive components, in three-dimensional space. Bends are located by defining the X, Y, and Z coordinates of the three points on the tube’s centerline: Each line of tangency and the theoretical intersection of both end tangents. This manner of specifying the bends is precise, of course, but causes difficulties in translating rectangular coordinates into bend data for machine programming. Use our Bend Data Calculator under the Black Art section of the website to quickly perform this translation. Compare bend data.

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.
