Abrasive water jet drilling of float glass and characterization of hole profile
- 2 Downloads
The applications of glass are tremendous since prehistoric period. Glass being brittle, amorphous material, it is highly difficult to carry out its machining using conventional methods. As abrasive water jet is a versatile non-traditional machining process, the current study uses Abrasive Water Jet (AWJ) for drilling glass. Among the various types of glass, most fragile glass type—float glass is used for study. Appropriate process parameters are used for machining based on the results and observations from preliminary experimentation. Also the Taguchi design is selected to carry out experimentation for all the possible combinations. The evaluation process of the drilled hole is carried out using optical profile projectors—to view the hole profile; Coordinate Measuring Machine (CMM)—to measure circularity and cylindricity; and Scanning Electron Microscopy (SEM) to observe the chipping and cracks developed during machining. Based on the deviation in hole profile, kerf analysis is carried out. Based on all the input and output parameters quantified, Analysis of Variance (ANOVA) is carried out to determine the most influential parameters. Finally based on the results obtained, for the experimented conditions and equipment used, Abrasive water jet drilling process is not recommended for drilling smaller diameter holes in float glass.
