Method and system for defining the position of a fastener with a peen mark

A system for positioning and drilling an opening configured to receive a fastener, the system comprising:

• 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, wherein the dot peen marking system is further configured to form the peen mark at a predefined orientation as defined by an predefined angle between a central axis of the peen mark and a surface in which the opening is to be drilled, and wherein the dot peen marking system is further configured to form a plurality of peen marks in a predetermined pattern on the workpiece at the location;
• and
• a robot comprising a vision system configured to identify the peen mark on the workpiece and to identify the predefined orientation of the peen mark and a drilling machine configured to drill the opening configured to receive the fastener at the location designated by the peen mark and at the predefined orientation of the peen mark.
