This research investigates machining schemes for dicing soda lime glass in order to reduce the damage in the processes. Ductile machining and brittle machining of glass are first analyzed based on fracture mechanics and then verified by experiments. Experiments with various machining schemes including scribing-then-breaking, direct-dicing and dicing-then-breaking processes for soda lime glass are then conducted. Experimental observations showed the following results. (i) The critical depth of cut (CDOC) for soda lime glass is between 0.4μm and 0.8μm that matches theoretical prediction, 0.78μm, based on fracture analysis. (ii) The scribing-then-breaking machining scheme results in less damage than the regular slicing process. The DOC of scribing, however, must be in the ductile-brittle region to achieve this result. (iii) Defect due to dicing on the back surface is higher than that on the front surface in one-step dicing through process. Dicing defects can be effectively reduced by decreasing the feed rate or increasing the dicing speed.
