If the radius value is incorrect, then the Feed motion calculated will probably be incorrect. For example, a 90 degree bend angle on a 70 mm radius will move the Feed axis about 110mm. However, if your bender actually uses a 50 mm bend die, then the correct Feed axis motion is about 79mm. The difference of 31mm could easily cause the Feed axis to show a fault condition. | If the radius value is incorrect, then the Feed motion calculated will probably be incorrect.

During Feed-Bending it is possible to experience a Feed Axis Fault that is caused by the wrong tool radius values or an incorrect Feed Axis Adjust % value. Both are in the Tool Page.
Quick indicators that should make you suspect that this is the case:
- The Feed Axis faults especially on large angle bends
- The Feed Axis does NOT fault when moving the bender through the cycle with no material in the machine.
Diagnosing the Problems
|
Possible Problem: The Centerline Radius values do not to match the bend die radii on the bender.
|
|
|
Possible Problem: The Feed Axis Adjust % Value is not set to the proper value in the Tool page.
That calculates to -14% elongation |
