System for processing a workpiece
A system ( 40 ) for processing a workpiece includes a support surface ( 88 ) for supporting a workpiece ( 44 ). The system ( 40 ) includes a processing tool ( 92 ) movable with respect to a processing path. The system ( 40 ) includes a sensor carriage ( 408 ) movable along a scan axis and having a light source ( 476, 515, 550, 586 ) located to emit a light beam at an angle to the scan axis onto a target surface of a workpiece ( 44 ), and a camera ( 484, 522, 558, 594 ) configured to record location data of the light beam on a target surface of a workpiece ( 44 ) as the sensor carriage ( 408 ) moves along the scan axis. The system ( 40 ) includes a control system for generating a three-dimensional point representation of a workpiece surface from the light beam location data, to control movement of the processing tool ( 92 ) based on the three-dimensional point representation of a workpiece ( 44 ).
