Experimental Research on 3D Ultraviolet Laser Precision Marking Processing Technology

Abstract

In this paper, in view of the complexity of the 3D laser marking, 3D ultraviolet laser precision machining process test is described. Firstly, the principle of ultraviolet laser processing technology and 3D surface texture mapping method were studied for laser marking of 3D surface. Second, through 3D ultraviolet laser test bench, with nonmetallic material as test object, test method and 3D ultraviolet laser marking processing was designed comparing with the 1064nm infrared laser marking. Experimental researches show that the precision of 3D ultraviolet laser marking is higher than infrared laser marking for three-dimensional parts.
