Glass is one of the most difficult materials to be machined due to its brittle nature and unique structure as frequent occurrence of fracture and edge chipping during machining has to be avoided. To minimize edge chipping of the machined glass, which is common when cutting materials harder than 50 HRC, adopting right parameters is required followed by additional effort and cost. This article presents experimentation in minimizing the edge chipping for glass milling operations using an internal cubic boron nitride grinding tool by optimizing the machining parameters. Taguchi optimization method is the most effective method to optimize the machining parameters, in which the most significant response variables affecting edge chipping could be identified. In glass milling operation, several machining parameters are considered to be significant in affecting edge chipping. These parameters include lubrication pressure and direction, feed rate, spindle speed, and depth of cut. The standard orthogonal array of L 16 (44) is used, while the signal-to-noise response analysis and analysis of variance methods are carried out to determine which parameters are statistically significant. Finally, confirmation tests are carried out to investigate the optimization improvements.
