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.
Diagnostic 1 - Check the Bend Die Radius Values
|
Possible Problem: The Centerline Radius values do not to match the bend die radii on the bender.
|
|
Diagnostic 2 - Check the Feed Axis % Values
|
Possible Problem: The Feed Axis Adjust % Value is not set to the proper value in the Tool page.
Enter that value into the Feed Adjust Percent field and press AutoBuild |
