| 摘 要： | 为了了解五轴磨床中杯形砂轮用于球面工件磨削的特点,通过坐标变换方法,给出了加工球面时杯形砂轮一点的磨削轨迹方程;基于轨迹方程,分析了磨削形态与加工参数之间的关系,导出螺距公式,提出条纹主带概念;最后进行了运动学分析,并依据杯形砂轮平面磨削实验结果,给出了杯形砂轮的理论磨削力变化曲线.分析表明,杯形砂轮加工球面的磨削形态近似对称,但磨削条件是不对称的.

| Abstract: | In order to understand the grinding characteristics in 5-axis spherical precision cup wheel grinding,the grinding trajectories equation was given in this paper referring to a single point of cup wheel using coordinate transform.Relationship between grinding topology and processing parameters was discussed based on the trajectories equation,and the formula of screw pitch was derived and the concept of trajectories' main band was introduced.In the end,kinematic analysis was carried out,and the curve of the th... |
