Minimum Leg Length.

Find the flange that fits.

Compare Xeon die openings and minimum leg lengths for your material thickness.

01 / Tooling & flange reference

Will your leg reach?

Choose catalog stock, a die, and a 45°, 90°, or 135° inside angle to check your outside flange length.

Use the outside formed leg, measured from the theoretical outside corner to the cut edge. See the sketch below.

Die selection

Auto uses the stock’s assigned die when available. For custom thicknesses, it screens the 6–12× V/T window and chooses the closest opening to 8× thickness.

The dashed corner is the theoretical outside apex. Measure b along the flange to the cut edge. α is the angle between the inside faces; the sketch is not to scale.

Your leg comparison

TRUMPF reference ↗

Compare your five dies.

Flange values follow the selected inside angle. 90° uses TRUMPF references; 45° and 135° use geometric estimates. Select a die to check its setup.

Use the right reference.

At 90°, use the TRUMPF die-specific minimum side-length reference, published for maximum sheet thickness and minimum punch radius. At 45° and 135°, the calculator uses HARSLE’s generic flange estimate. These estimates are for planning; they are not verified limits for Xeon’s dies.

Check the complete bend.

A leg above the reference or estimate still needs material, load, backgauge, sensor access, and collision checks. Die and assigned-punch angles are screened, but springback can require a tighter forming angle. Acute bends, hems, offsets, and sensor-controlled setups need a forming review. Explore Bend Inner Radius, Pressing Force, or the Bend Simulator.
