| 摘 要： | 为磨削出微沟槽结构化表面，设计一种将金刚石丝锯紧密缠绕在基体上的新型砂轮，提出相应的结构砂轮平面磨削沟槽结构的方法。首先，建立砂轮几何模型与数学模型并得出磨粒运动轨迹方程；其次，理论分析磨削沟槽表面的创成机理及磨削参数对沟槽形貌的影响；最后，通过仿真和实验验证新型砂轮磨削沟槽结构的可行性和不同磨削参数下的沟槽结构形态。研究结果表明:绕丝结构化砂轮可以平面磨削出结构化沟槽表面，且改变磨削用量能磨出不同尺寸的参数与排布的沟槽结构。

| Abstract: | To obtain structured surface with micro grooves, a new type of the grinding wheel closely wound by diamond wire saw was designed as well as a method to grind grooved structure with corresponding grinding wheel. Thus, the geometrical and mathematical models of the grinding wheel and the kinematical trajectory equation of the abrasive particles are established. The generating mechanism of grooves and the influences of the grinding parameters on the grooves morphology are analyzed. The feasibility of the structured wheel in grinding grooves are verified by simulation and experiments, as well as the grooves under different parameters. The results show that the grinding wheel could grind structured surface with grooves, and that the sizes and arrangements of grooves are changed with grinding parameters. |
