PROGRAM-CONTROLLED PROCESS

摘要

A drilling machine (16) drills at a multiplicity of target locations on a component (10). Two robots (12, 14), calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system (32) ascertains the position of the component (10) relative to the drilling machine (16). The movement of the robots (12, 14) is effected by means of commands generated by means of off-line programming (52). The component (10) is moved relative to the drilling machine (16) to a target position, ready for drilling, by means of a closed-loop process (50) in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected.
