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.
