Abstract
A system and method for laser processing a complex pattern and a perimeter around the complex pattern on a moving web, the complex pattern and the perimeter processed continuously with a single laser. The complex pattern may be a plurality of holes such that cutting of the perimeter forms a disk having multiple holes. The plurality of holes are interior to the disk and laser processed using a camming program while a web of material is continuously moving. The laser is then repositioned to cut the perimeter while the laser remains on and the web is continuously moved. The multi-hole disk may be cut from a continuous roll of abrasive material.
