Study on machinability for laser-assisted machining of hydraulic carbon-graphite seal rings
摘要
Abstract
To perform high efficient turning of hydraulic carbon-graphite seal rings, the laser-assisted machining of the material of carbon-graphite seal ring was conducted using laser pre-heating. The material of carbon-graphite seal rings has the characteristics of high strength and high hardness, and is typical non-metallic difficult-to-machine material. The laser-assisted machining heats the workpiece using laser beam, improving machining efficiency as well as reducing cutting force and tool wear. The turning process of carbon-graphite M104 seal ring was focused on, and the conventional machining was compared with the laser-assisted machining. The experimental process of laser-assisted machining was designed and reasonable process parameters were selected. A high cutting efficiency was obtained. The main cutting force and radial force decreased by 23. 5% and 19. 9% compared with conventional machining. The temperature distribution in the cutting zone of laser-assisted machining is similar to conventional machining. The laser-assisted machining has less tool wear and can get a better surface quality.关键词
