Abstract
A system for laser processing a work piece surface with a laser processing beam includes a processing beam delivery source (205) optics (210, 230) for focusing the processing beam at a surface of the work piece, a viewing camera (250) configured coaxially and coincidently focused with the processing beam (207) at beam impinge point (245) on the work piece (100). The system further includes a computer (510) and processor (512) for displaying an image of the work piece (100) and a cursor (600) superimposed thereon on a monitor (560). One or more movable mirrors (320, 325) are provided movably mounted on galvanometers (335, 340) controlled by the processor (512) to direct the processing beam to selected points on the work surface for processing, (e.g. by laser spot welding). The system further includes an input device such as a mouse (520) for positioning a movable cursor (600) on image points of the work piece image and for selecting the image point for laser processing. The image points may be stored in a memory (514) as a pattern of image points laser processed as a patter under automatic control by the processor (512).
