1. A method of ablating debris from a support surface during repeated cuttings of segments of a material along a common cutting path, comprising:

  • (a) positioning the common cutting path in a first position with respect to the support surface;

    (b) directing a laser along the common cutting path in a first cutting to cut a first segment of the material and form a first adjacent debris ridge;

    (c) disposing a second segment of the sheet material on the support surface; and

    (d) displacing the common cutting path for a second cutting to a second position positioned over a portion of the first adjacent debris ridge such that upon directing the laser along the portion of the common cutting path in the second cutting, the laser penetrates the second segment of the sheet material and contacts the portion of the first adjacent debris ridge to substantially ablate the debris.
