Abstract

The cup-shaped grinding wheels with arc-shaped edges provide a satisfactory precision grinding solution for high-accuracy optical surfaces on hard and brittle materials. However, the complex profile of the arc-shaped edges of cup-shaped grinding wheels makes them challenging to truing. This paper proposes an on-machine truing technique targeting cup-shaped grinding wheels with arc-shaped cutting edge. First, a mathematical model was established to simulate the three-axis of on-machine truing the arc-shaped cutting edge using a diamond roller. Based on this model, a theoretical analysis is conducted to investigate the impact of tool setting errors, measurement errors of the diamond roller, and the pose error on truing accuracy. A compensation method was proposed, and experimental results validated its effectiveness. To investigate the grinding performance of cup-shaped grinding wheels after truing, a complex component is ground using a truing diamond grinding wheel. The experimental results demonstrate that this method enables precise on-machine truing of the arc-shaped edges of cup-shaped grinding wheels and is efficient. The average dimensional accuracy of the grinding wheel's arc-shaped edge is reduced to 1.5 μm, with the profile accuracy (PV) of 0.89 μm.

弧刃杯形金刚石砂轮的机内精密加工及误差补偿。

杯形圆弧边砂轮为硬脆材料上的高精度光学表面提供了满意的精密磨削解决方案。然而，杯形砂轮圆弧边缘的复杂轮廓给磨削带来了挑战。提出了一种针对弧形刃口杯形砂轮的机内修边技术。首先，建立了利用金刚石滚轮对弧形刃口进行机内修整的三轴数学模型；在此基础上，从理论上分析了对刀误差、金刚石滚子测量误差和位姿误差对加工精度的影响。提出了一种补偿方法，实验结果验证了该方法的有效性。为了研究杯形砂轮在精磨后的磨削性能，采用精磨金刚石砂轮对某复杂部件进行磨削。实验结果表明，该方法能实现杯形砂轮圆弧边的机内精密加工，具有较高的加工效率。砂轮弧形边缘的平均尺寸精度降至1.5 μm，轮廓精度（PV）为0.89 μm。
