Abstract
A method and apparatus for cleaning a support surface during successive cuts of a sheet material along a common cutting path by a laser. The method includes offsetting the location of the common cutting path with respect to the support surface for subsequent cuts. The offset distance is sufficient to align a portion of the common cutting path with a portion of the ridge of debris formed during a previous cut such that upon tracing the subsequent path with the laser, the previously formed ridge of debris is ablated.
