摘要

摘要: 以氧化锆陶瓷为研究对象，基于纵扭超声矢量分解原理，建立了单颗磨粒运动轨迹数学模型。借助MATLAB仿真软件，对比分析了普通磨削与纵扭超声磨削的运动轨迹，探讨了工艺参数对纵扭超声磨削运动轨迹的影响规律；同时通过普通磨削和纵扭超声磨削试验，研究了工艺参数对氧化锆陶瓷表面形貌的影响。结果表明：普通磨削与纵扭超声磨削运动轨迹仿真结果均与试验结果相吻合，验证了该运动轨迹数学模型的正确性；与普通磨削相比，纵扭超声磨削磨痕均匀、沟槽光滑，工件加工表面形貌得到明显改善。

Abstract: Taking Zirconia ceramics as the research object, a mathematical models of single abrasive particle trajectory is established based on the principle of longitudinal torsion ultrasonic vector decomposition. With the MATLAB simulation software, the conventional grinding and longitudinal torsional ultrasonic grinding are analyzed and the influence of process parameters on the trajectory of longitudinal torsional ultrasonic grinding is discussed. Experiments of conventional grinding and longitudinal torsional ultrasonic grinding on zirconia ceramics are performed to analyze the trajectories of conventional and longitudinal torsional ultrasonic grinding, and the effect of processing parameters on the surface morphology are disclosed. The simulation results of motion trajectory of conventional grinding and longitudinal torsional ultrasonic grinding are consistent with the experimental results, which verifies the correctness of the mathematical model of the trajectory. Moreover, the machined surface morphology with uniform wear marks and slight grooves produced by longitudinal torsional ultrasonic grinding is obviously improved compared with the conventional grinding.
