Kerf Compensation

Laser cutting has a kerf (the part that is lost during cutting), which makes the size of the actual cut part deviate from the theoretical size of the part. This operation enables geometric compensation for deviations.

Kerf compensation types are divided into:

• All Shrink: Shrink the cutting area for all selected parts.

• All Expand: Expand the cutting area for all selected parts.

• Unfill: Shrink; Fill: Expand: shrink the cutting area for parts with unfill attribute, and expand the cutting area for parts with fill attribute.

Prerequisite:
