Abstract
The discrete element method (DEM) is applied to glass micromachining in this study. The indentating, cutting, micro milling process are simulated by the established DEM matching the main mechanical properties of glass in three sets of standard tests. Results show that the vertical damage depth is prevented from reaching the final machined surface in cutting process. Tool rake angle is the most remarkable factor influencing the chip deformation and cutting force. The final machined surface is determined by the minimum cutting thickness per edge. Different cutting thickness, cutter shape and spindle speed largely affect the mechanism of glass.
