UNCONTROLLED COPY

DEC-CTL-004

Burr Procedure
1. Burr must be checked, at minimum, once per coil by helper.  
2. Burr cannot be more than 10% of material thickness. Note: Burr max does not apply to Grade 100 or CMC A514 Grades, these are best effort.  
3. If burr is greater than 10% of material thickness, Operator must close gap on the shear blade.  
4. If Operator sets gap at 10% and the burr is still greater than 10%, Operator must flip/change shear blades.
