A method of laser milling an aperture in a workpiece for use with manufacturing ink-jet nozzles includes initially illuminating a surface of the workpiece with a laser beam at a point within an outer perimeter of a desired aperture and a distance away from the outer perimeter sufficient to substantially avoid initial ablation of the outer perimeter. The laser beam is driven substantially in the direction of the outer perimeter at a variable rate controlled to avoid deformation of the outer perimeter. Material of the workpiece is ablated in a pattern designed to substantially remove material within the outer perimeter, thereby forming the aperture.
