Modeling and Simulation of Temperature Field of Nano-zirconia Ceramics Precision Grinding

摘要

Based on the analysis of the processing properties of nano-zirconia ceramic materials, a theoretical model for nano-zirconia grinding temperature field was established, and the three-dimensional model was simulated and analyzed in different grinding conditions using ANSYS software. The results showed that: with the grinding wheel cutting into the work-piece, the temperature of the work-piece rose sharply, and then leveled off, with a high temperature gradient on the surface of work-piece. If the work-piece was long enough, there would be a stable area; with the grinding depth of cut increased, a local high temperature would appear in grinding contact zone, which made the work-pieces burnt.
