A Global Automaker Selects Dynalog for Robotic Accuracy for their Laser Cutting Application

Dynalog is selected by a global automaker to provide Absolute Accuracy, Temperature Compensation, and Guidance for robots performing laser cutting process. A robot-mounted sensor is utilized to acquire the calibration and guidance measurements. A robot-mounted sensor reduces the number of sensors required to perform the robot guidance process. These laser cutting cells will soon go into full production.

Ceramic based calibration targets are mounted within the robot-cells. The measurements of the calibration targets are utilized by Dynalog’s DynaFlex software to identify the Absolute Accuracy robot-cell parameters. Furthermore, periodic measurements of the calibration targets are obtained automatically (few measurements during transfer of the car), and used to identify the change in the robot-cell parameters. The critical robot laser cutting positions are compensated for the change in the robot-cell parameters. Moreover, during each production cycle a few car datum features are measured by the robot-mounted sensor. The accurate location of the car is identified based on these measurements.
