Optimization of the USM process of PTFE using Grey Relational Analysis
Pavan Ghelani,  Ujawala Salunkhe
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.
