Cut-Edge Damage in Narrow CRGO Laminations

The same edge damage occupies more of a narrow strip. Shearing deforms a band beside each cut. In that band, disturbed magnetic domains can reduce permeability and raise local loss. Keep the damaged band the same width, then make the strip narrower. Its share grows, and flux can crowd toward the centre. The article gives no damage width or loss percentage. Blade condition matters: a dull edge can widen the affected band. Match clearance to sheet thickness and regrind from measured burr and edge quality. Use stress relief only when the grade and process permit it; stress scribed refinement can be erased. Assess building factor for the actual strip widths, not one catalogue value.
