Abstract
A method of machining a mold surface using laser includes the steps of preparing a laser device and an optical zoom lens assembly disposed in front of the laser device; using a computer to compute a sectional curvature of the mold surface to be machined, so as to obtain parameters for controlling variance in laser focal length; and machining the mold surface twice to remove mold material from desired areas and to polish the mold surface, so that the machined areas are blended with the original coarse surface to show the designed patterns while showing a polishing effect. Therefore, a product molded using the machined mold would show different changes or refraction of light.
