System for processing a slab having a top polished face and related method
A system processes a stone slab having a top polished face and bottom surface. An imaging device receives and displays a digital image of the top polished face of the slab. A controller overlays a slab cut layout on the digital image of the top polished face, generates a digital slab layout file containing digital data representative of the top polished face and its slab cut layout referenced to the top end of adhered reference markers, mirror images the digital slab layout file, and projects the mirror imaged locations of the reference markers to facilitate alignment of the bottom ends of the adhered laser markers with the respective projected reference marker locations when the slab is upside down for cutting in a slab cutting position.

a controller connected to the imaging device and configured to,
overlay a slab cut layout on the digital image of the top polished face,
generate a digital slab layout file therefrom containing digital data representative of the top polished face and its slab cut layout referenced to the top end of the adhered reference markers,
