氧化锆陶瓷磨削表面质量仿真与实验研究
Simulation and Experimental Study on Surface Quality of Zirconia Ceramic Grinding
摘要
Abstract
The study was carried out to find out the effects of wheel speed, grinding depth, and other grinding parameters on the surface qualities of zirconia ceramic workpiece under the condition of high speed.Single-grit simulation has been utilized to analyze the influence of abrasive cutting depth and cutting speed on grinding force and surface morphology.Through the grinding experiment, in which a diamond grinding wheel was equipped to grind zirconia ceramics, grinding forces and surface topography images were obtained and used to verify the simulation results.With the increase of the grinding depth from 2 μm to 8 μm, the grinding force of single diamond abrasive grain was increasing monotonically, and the workpiece surface quality was gradually deteriorated.When the grinding depth was kept at 2 μm, the workpiece surface morphologies became less dependent on the wheel speed;when the grinding depth exceeded 4 μm, the wheel speed increase could effectively reduce the broken damage on the grinding surface.关键词
