Abstract Float glass has immense applications such as sensor glass, micro-processor glass and decorative glass; because of its exceptional wear resistance, chemical and thermal characteristics. Nevertheless, researchers are still bearing decisive issues, which affect its application. These issues are profile inaccuracy and chipping because of its poor machining characteristics and hence high precision machining. The objective of the present study is to condemn the chipping related hindrances while using multi-shaped diamond abrasive tools to create blind holes. The tools, which applied, are named as hollow abrasive tool, pinpointed conical tool, flat cylindrical tools and concave circular tool. The experimental trials were performed by rotary ultrasonic drilling (RUD) and CNC conventional drilling (CD). The actual industrial conditions and parameters were considered throughout the experimentation. Physics behind the formation of chipping on hole periphery by RUD and CD are revealed. In addition, individual mechanisms of multi-shape tools with respect to chipping are analyzed. The results show that RUD process has attained the smallest measurement of chip radial distance as compared to CD for all types of tool. Finally, the concave circular tool is found as the best tool particularly to get least chip radial distance during drilling i.e. 0.1145 mm.

旋转超声钻孔与常规钻孔浮法玻璃碎屑力学对比分析：用于多形刀具

摘要 浮法玻璃在传感器玻璃、微处理器玻璃、装饰玻璃等方面有着广泛的应用；由于其卓越的耐磨性、化学和热特性。尽管如此，研究人员仍然面临着影响其应用的决定性问题。这些问题是轮廓不准确和碎屑，因为其加工特性差，因此加工精度高。本研究的目的是在使用多形金刚石磨具制造盲孔时谴责与崩刃相关的障碍。所应用的刀具有空心磨具、尖锥刀具、扁圆柱刀具和凹圆刀具。实验试验通过旋转超声钻孔 (RUD) 和 CNC 常规钻孔 (CD) 进行。在整个实验过程中考虑了实际的工业条件和参数。揭示了 RUD 和 CD 在孔周边形成碎屑背后的物理原理。此外，还分析了多形状刀具在崩刃方面的各个机制。结果表明，对于所有类型的刀具，与 CD 相比，RUD 工艺实现了最小的切屑径向距离测量。最后，凹形圆形刀具被认为是最好的刀具，尤其是在钻孔过程中获得最小切屑径向距离，即 0.1145 毫米。结果表明，对于所有类型的刀具，与 CD 相比，RUD 工艺实现了最小的切屑径向距离测量。最后，凹形圆形刀具被认为是最好的刀具，尤其是在钻孔过程中获得最小切屑径向距离，即 0.1145 毫米。结果表明，对于所有类型的刀具，与 CD 相比，RUD 工艺实现了最小的切屑径向距离测量。最后，凹形圆形刀具被认为是最好的刀具，尤其是在钻孔过程中获得最小切屑径向距离，即 0.1145 毫米。
