Abstract

Considering that optics fabrication is based on a constant material removal rate and polishing tool characteristic during the polishing run, one parameter named temperature, which is ignored frequently on account of the consciousness of its unimportance, has been researched in fluid jet polishing process. Thermal sources resulting in the increasing of slurry temperature have been analyzed, and the analysis is proved by simulation with population balance modeling method by Computational Fluid Dynamics Software and experiments. Researches show that the slurry temperature is increasing under way of polishing process before achieving a steady value when the produced heat energy is equal to the one diffusing to surrounding. Experiment show that the temperature of slurry change scarcely with the raise of pressure, and the temperature of polishing region increases with the raise of pressure, because the heat energy produced by impact action and friction diffuse in slurry and workpiece increases with the raise of velocity.
