Double-beam five-axis numerically controlled laser polishing method

Abstract

The invention discloses a double-beam five-axis numerically controlled laser polishing method. The method comprises the following steps that A, firstly, two three-dimensional galvanometer systems capable of performing three numerically controlled moving shafts are arranged on laser polishing equipment to form a double-beam three-dimensional galvanometer system, a fiber infrared continuous laser passes through the first three-dimensional galvanometer system and applies a focused light spot on a three-dimensional curved surface of a to-be-polished workpiece, a multi-band pulsed laser passes through the second three-dimensional galvanometer system and also applies a focused light spot on the three-dimensional curved surface of the to-be-polished workpiece. The double-beam five-axis numerically controlled laser polishing method has the advantages that 1, the method can be applied to laser polishing of a plastic injection mold cavity and a blow mold cavity; 2, laser polishing can be performed on a 3D glass shell of a mobile phone; 3, precise laser polishing can be performed on optical glass; 4, polishing can be performed on the three-dimensional curved surface of parts processed by additive manufacturing (3D printing); 5, laser polishing can be performed on the three-dimensional shaped curved surface of other product parts.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a double-beam five-axis numerical control laser polishing method. Background technique [0002] Modern manufacturing needs to polish the surface of product parts such as metal and non-metal (glass, ceramics, quartz, etc.), and some even require polishing to reach the highest level of mirror surface, such as handicrafts, artworks, decorations, and plastic mold cavities, etc. Surface; The surface of metal parts 3D printed by SLM and other technologies is quite rough, and often requires subsequent polishing. At present, most of this polishing work still relies heavily on manual work, with poor polishing accuracy, low efficiency, and lack of consistency and stability in polishing quality. What's more, manual polishing work is extremely monotonous and boring. With the development trend of higher and higher integration of manufacturing process automation, fewer and fewer worker...

Problems solved by technology

Laser polishing technology is one of the effective ways to improve the efficiency of the traditional polishing process, but the current application is limited to the polishing of the plane of the part, and the technical polishing technology of the three-dimensional curved surface or special-shaped curved surface is still in the stage of technical research
