Ultrasonic drilling is effective method compared to conventional drilling as in conventional process too much energy wasted to produce unwanted chips. It is a non thermal process so PTFE material not thermally damage with USM. The objective of this study is to check the feasibility of polytetrafluoroethelene for a ultrasonic machining. The effect of Pressure, Amplitude & Thickness of PTFE sheets on MRR, Taper & Overcut can be studied and determined. The effect of parameters on the process can be studied that can be useful for various analysis. The factors affecting Ultrasonic Machining performance are found from literature review & the effect of same is to be experimentally investigated. Full factorial Design for 3 input parameter at 3 level with 2 replication chosen for analysis. Thickness is found most significant parameter for MRR. The results of grey optimization shows that for both rough finishing as well semi-finishing hole, higher GRG achieved at medium thickness & amplitude and for maximum pressure.
