摘要：A laser cutting device () is configured to etch an inner surface of a journalbearing (). The laser cutting device () includes a laser (); a beam directing tool () that
receives a beam () emitted from the laser () and selectively changes the direction of travelof the beam (); a fixture () that supports the journal bearing () in a desired positionrelative to the beam directing tool (); an actuator () connected to one of the beamdirecting tool () and the fixture (), the actuator () providing relative movement betweenthe beam directing tool () and the fixture (); and a controller () that controls the intensityand duration of the beam () emitted from the laser (); and the actuator (), wherebymaterial can be re moved from a surface of the journal bearing () to a precise width anddepth, and in any pattern.
