Method of determining whether or not result of processing process of laser processing apparatus is acceptable
There is provided a method of determining whether or not a result of a processing process of a laser processing apparatus is acceptable including a laser processing step of applying a laser beam to predetermined processing regions of a workpiece held on a chuck table, thereby performing a piercing process on the workpiece, an image capturing step of capturing images of all the processing regions while moving the image capturing unit and the workpiece relatively to each other, a detecting step of detecting regions where light is not transmitted through the workpiece among the processing regions in the image captured in the image capturing step, and a determining step of determining that the laser processing apparatus needs to be readjusted if the regions where light is not transmitted through the workpiece is equal to or more than the predetermined quantity.
Intelligent non-autogenous metalworking systems and control logic with automated wire-to-beam alignment
Presented are intelligent non-autogenous metalworking systems and control logic for automated wire-to-beam alignment, methods for making/using such systems, and robot-borne laser welding/brazing heads with closed-loop control for real-time wire alignment. A method for controlling operation of a non-autogenous workpiece processing system includes a system controller receiving sensor signals from a position sensor indicative of a location of filler wire discharged into a joint region by a wire feeder. Using the received sensor signals, the controller determines a displacement between the wire location and a location of a beam emitted onto the joint region by a beam emitter. If the wire displacement is greater than a threshold wire displacement value, the controller responsively determines a corrective force calculated to reduce wire displacement to below the threshold wire displacement value. The controller then commands the actuator to pivot the processing head to thereby apply the corrective force to the discharging filler wire.

INITIAL DISTANCE APPROACH FOR LASER PROCESSING
In an example method, a laser processing head is moved from an entrance region over a workpiece to a starting position above the workpiece. During this time, a distance control system is used to control the distance between the laser processing head and the workpiece based on measurements obtained from one or more distance sensors. Further, the laser processing head is moved from the starting position to a position beyond an edge of the workpiece. During this time, the distance control system is disengaged. When the laser processing head reaches the position beyond an edge of the workpiece, laser emission is initiated, and the laser processing head is moved back towards the starting position. Upon reaching the starting position, the distance control system is reengaged. The laser processing head is subsequently moved along a pre-determined path to cut the workpiece.
