摘要: 为得到超声振动辅助平面磨削过程中超声振动方向对磨削力的影响规律,提出了不同超声振动方向的超声振动辅助平面磨削工艺方法。系统地分析了超声振动方向的改变对磨粒运动轨迹的影响,利用DEFORM-3D软件对比分析了不同超声振动方向对磨削加工过程中磨削区的应力场、磨削力的影响,使用滚动轴承钢GCr15进行了磨削试验。试验结果表明:倾角α(超声振动方向与机床坐标系X轴夹角)增大的过程中磨削力呈先减小后增大的变化趋势;同时经过试验验证,仿真试验所得法向磨削力误差为5.23%、切向磨削力平均误差为8.12%,有较高的精度和可靠性。

Abstract: The method based on variable angle of ultrasonic vibration assisted grinding was put forward to identify the relationship between direction of ultrasonic vibration and grinding force. The trajectory of grit in contact zone was analyzed. The stress field of contact zone and the grinding force, which were based on the different directions of ultrasonic vibration, were simulated and analyzed by Deform-3D. A series of grinding experiments of GCr15 were conducted. It demonstrates that with the angle α increasing, the grinding force firstly decreased and then increased. The experiment results showed that the error of normal force is 5.23% and the error of tangential force is 8.12%. The model has a higher accuracy.

Key words: ultrasonic vibration assisted grinding, direction of ultrasonic vibration, simulation, grinding force
