Constant kerf dieboard cutting system using laser and vision

Abstract

Laser cutting a dieboard using a laser cutting system, including: setting a width of material to be removed from the dieboard using the laser cutting system; capturing an image of the width of the material removed by the laser cutting system using at least one image capture unit; measuring the captured width of the material captured on the image using the at least one image capture unit; and comparing the measured width of the material to the set width of the material, and moving a laser head of the laser cutting system up and down to adjust a focal length of the laser cutting system and moving the laser head of the laser cutting system sideways to adjust a speed of the laser head, until the measured width and the set width are substantially similar.

Dependencies are inferred from the claim text.
