USM has become an important and cost-effective method of machining extremely tough and brittle materials. It is widely used in the process of drilling and machining on sections of complex geometry and intricate shapes. The work piece material selected in this experiment is GLASS FIBRE REINFORCED PLASTIC (GFRP) taking into account its wide usage in industrial applications. In today’s world GFRP contributes to almost one third of the world’s production and consumption for industrial purposes. This material is not used for traditional machining due to chipping or fracturing. Many similar problems can be successfully solved using ultrasonic technologies. The input variable parameters are type of tool material, frequency, amplitude, concentration in usm. Taguchi method is applied to create an L’18 orthogonal array of input variables using the Design of Experiments (DOE). The effect of the variable parameters mentioned above upon machining characteristics such as Material Removal Rate (MRR), Surface Roughness (SR) and Tool Wear Rate (TWR) studied and investigated. The tool material is titanium (ASTM-1) and carbide (k20). All the calculations are made with the help of MINITAB 16 software. Most influence factor for MRR is observed as amplitude with 67.27% contribution. For SR amplitude with contribution of 33.3% and TWR is observed as frequency with 44.4% contribution plays an important role.
