A method and system are provided to position and drill an opening for a fastener through one or more workpieces. In the context of a method, a peen mark is formed on a workpiece at a location at which the opening is to be drilled. The method also includes utilizing a robotic vision system to identify the peen mark on the workpiece and thereafter drilling the opening configured to receive the fastener at the location designated by the peen mark. In the context of a system, the system includes a dot peen marking system configured to form a peen mark on a workpiece at a location at which the opening is to be drilled. The system also includes a robot comprising a vision system configured to identify the peen mark on the workpiece and a drilling machine configured to drill the opening at the location designated by the peen mark.

A tool center point calibration device includes a laser light source and a semi-transparent mirror configured to split a light beam of the laser light source into the first light beam and the second light beam. The second light beam is at of about a 90 angle to the first light beam. A first light detector at the first light beam generates a first signal when the first light beam is interrupted, and a second light detector at the second light beam generates a second signal when the second light beam is interrupted.

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.
