Effect of laser abrasive belt processing on surface quality of titanium alloy TC17Effect of laser abrasive belt processing on surface quality of titanium alloy TC17

Abstract

Abstract Due to its low thermal conductivity, work hardening and other characteristics, titanium alloys are prone to shortcomings such as large cutting force and poor processing quality in the processing process. Laser-assisted grinding (LAG) can significantly improve its processing performance, but the mechanism of synergistic parameters between laser and abrasive belt on surface quality has not been clearly revealed in the laser-assisted belt grinding process. Based on this, this paper proposes a method of laser-belt collaborative processing (LBCP), established a mathematical model of laser and abrasive belt co-processing, and reveals the collaborative processing mechanism. Through the LBCP experiment of titanium alloy TC17, the grinding force, surface morphology, and roughness of titanium alloy TC17 were investigated, and the effect of different collaborative processing factors on the surface quality of titanium alloy was studied. The results show that appropriately increasing the normal pressure will improve the surface quality of titanium alloy. The larger the laser incidence angle, the better the surface quality. Reducing the synergistic distance between the laser and the abrasive belt improves the surface quality. This study provides new ideas for laser-assisted processing of difficult-to-process materials.
