Abstract
Methods of creating various laser-defined control structures on pressure relief devices are provided that utilize a laser having a field of view that is smaller than the overall dimensions of the laser-defined structure to be milled into the pressure relief device. The methods generally involve partitioning the working surface of the device into a plurality of tiles within which a particular segment of the control structure will be milled. Upon milling of a control structure segment in one tile, the pressure relief device and/or laser is repositioned so that a control structure segment in another tile may be created.
