Description
To minimize fracture size in through-hole drilling of glass plate, this paper examines drilling behavior of commercial tool shape, as well as the availability of a tool shape designed by the authors. The chipping size occurring at the hole edge is related to the form of tool end and the chip elimination efficiency. The designed tool, which is an electroplated diamond tool with a diameter of 1 mm, has a unique shape. The tool shape has a hemispherical tool end and a few straight planes. During drilling, the hole enlarges gradually due to the hemispherical shape of the tool end. The occurrence of chipping at the edge of the exit hole is reduced because the hemispherical shape can reduce the abrupt decrease in drilling force. That is, large chipping and cracking corresponding to the hole diameter can be suppressed. In addition, the straight planes play a role in eliminating chipping, and the adhesion of chips is suppressed. The results of this investigate indicate that the designed tool allows drilling of drilling cycle.
