Borosilicate glass serves as the substrate of microdevices due to its good surface integrity and ability to withstand thermal shock. However, the brittleness and non-conductivity of glass makes it difficult to machine with high accuracy and precision using conventional and non-conventional machining processes. This Research focuses on machining of borosilicate glass using laser assisted abrasive jet machining. Laser assisted abrasive jet machining is a hybrid method of machining, which combines laser with abrasive jet in a sequential manner. Laser preheating is used to soften the workpiece, which in turn increases the machinability of material. The effect of process parameters like power, cutting speed and stand-off distance (SOD) on response parameters like material removal rate (MRR), Kerf width (Kw) and heat affected zone (HAZ) are discussed. Experimentation was designed based on Taguchi’s L9 orthogonal array. In addition, the Analysis of Variance is used to investigate the effect of cutting parameters on machining. The experimental results revealed that the developed hybrid machining process efficiently improves MRR and minimizes Kw and HAZ.
