Getting a grip
Setting the grip die securely in rotary draw bending requires close attention to three factors: the pressure exerted by the machine, the contact area, and the material’s coefficient of friction.

Selecting the right mandrel and wiper
Tube bender operators could rely on complex mathematical formulas and rules of thumb, but it’s much quicker to use a tooling chart. This sort of chart lists the two main bending criteria, D of bend and wall factor, on the X and Y axis, respectively. However, these charts have just two axes, and usually are based on bending mild steel to 180 degrees. Tube bending comprises many more variables, materials, and bend angles. Knowing how to make adjustments to compensate for additional factors is critical for successful bending.

The right stuff
The best material for a tube bending tool is the most cost-effective in terms of the ratio of tool life to tool cost. A cost-effective tool tends to wear out rather than break at the end of its service life. This article addresses choosing the optimal material for a rotary die tube bending machine's full toolkit.

Setup or cover-up?
Setting up the tooling for a tube or pipe bending machine isn't as simple as it seems. Many variables are involved, making this a difficult task. A further complication is the tendency for many operators to adjust various pressure settings to compensate for poor tooling setup. The bend might turn out okay, but at a cost—a loss of process control and shortened tool life. Using a simple four-step setup process is the key to good bending, process control, and optimal tool life. This setup procedure also facilitates troubleshooting.

The wiper die's feathered edge
The mechanical aspects of rotary draw tube bending haven't changed since modern tooling was developed 50 years ago. Likewise, the role of the tooling (mandrel, pressure die, bend die, and wiper die) hasn't changed. However, tube fabricators these days have many choices in regard to the tooling, especially wiper dies. Choices include material, rake angle, and whether the wiper die's feathered edge is fully machined or honed by hand.
