Effect of Process Parameters in the Conventional High-Speed Drilling of Glass

Glass has been widely used due to its superior wear and corrosion resistance. Demands for producing crack free, high quality holes in glass have been increasing for a number of applications. However, due to its brittle nature the fabrication of finely machined features has proved to be challenging due to complexities involving edge chipping, tool wear, dimension accuracy, heat fractures and material breakage, etc. The conventional drilling of glass is undertaken at low speeds, especially for large diameter holes, in order to offset the increased speed at which the outer cutting edge moves. But this in fact increases the machine time and the trust forces on the glass work piece. Hence water jet machining and laser machining are used in the industries for the drilling of glass. The objective of this paper is to determine the effect of parameters such as feed rate, material removal rate, thrust force and dimensional accuracy during high speed drilling in soda lime glass. MINITAB software is used to design the experimental conditions using the RSM technique and obtain the statistical data solutions based on the experimental results.
