Feedback Controlled Laser Machining System.

摘要

A system for machining a workpiece to desired finished workpiece specifications. The system comprises a system for producing a laser beam; a system for positioning the workpiece relative to the laser beam; a system for measuring the topography of the work piece and producing workpiece topography data; and a computer and control system operatively connected to the system for producing a laser beam, to the system for positioning the workpiece relative to the laser beam, and to the system for measuring the topography of the work piece and producing workpiece topography data. The computer and control system compares the workpiece topography data with the desired finished workpiece specifications and controls the system for positioning the workpiece relative to the laser beam so that the workpiece is moved with respect to the laser beam in a desirable fashion, within certain velocity, acceleration, and distance constraints. The computer and control system controls the system for producing a laser beam so that the laser beam machines the workpiece to the desired finished workpiece specifications.
