Ultrasonic machining is employed frequently for machining of brittle materials like glass, ceramics etc. Production of blanks by machining glass is required for wide variety of optical and other applicaitons. In this work, a full factorial experiment is designed to study the effect of process parameters on ultrasonic blanking of glass. The control parameters chosen are amplitude, pressure and thickness of the glass sheet being machined. Three levels of each of these parameters are selected giving 33 = 27 trials. The material removal rate is measured as response parameter. A velocity transformer with tool integral to the lower end is designed with annular cutting edge to increase the efficiency in cutting. Silicon Carbide abrasive particles are used with water as the abrasive slurry. The material removal rate is found to increase with increase in amplitude and pressure but decreases with increase in thickness of the work piece. ANOVA is carried out for the experimental results.
