UNDERSTANDING SPRINGBACK
Springback can be difficult to understand. As material is bent, the materials yield strength resists
being formed. As a final degree is reached, the machine will have enough power to hold the
bend at a set degree, but as the pressure of the machine is released, the material has a
resistance built in, so it “springs back”
Springback will vary with every size, type and wall thickness, so it will never be consistent from
size to size.
The best way to determine a materials springback is to do sample bends to 90 degrees until a
perfect 90 is obtained.
•
At that point document the actual machine degrees.
•
Full manual mode is the best place to do these tests.
•
Use the overbend amount and enter that value into the springback field.
MATERIAL SELECTION
When selecting materials keep these instructions in mind:
•
Material must be clean and dry. (without oil)
•
Material should have a smooth surface so it processes easily.
•
Dimensional properties of material must be consistent and not exceed the machine capacity
values.
•
Chemical structure of material must be consistent.
•
Buy certificated steel from the same vendor when possible.
CAUTION:
It must be determined by the customer that materials being
processed through the machine are NOT potentially hazardous to operator or
personnel working nearby.
