Precision profile grinding with textured diamond wheels is an alternative for generating microstructures on the ceramic mold for glass molding. In this work, a novel texturing strategy employing abrasive waterjet for superabrasive grinding wheels was proposed to generate controllable microtexture profile on the diamond wheel surface efficiently. The quadratic backward-eliminated regression models were developed using Box–Behnken response surface design in the abrasive waterjet micromachining of diamond grinding wheel sample. The effect of operating parameters and their interaction on the depth and width of groove were investigated. The surface speed and standoff distance were found to be main controlling variables on the depth and width of groove, respectively. A consistently good agreement was confirmed between the predicted values and the experimental values under acceptable errors.
