Abstract:
In the present study, a semi-empirical model is developed for predicting the material removal rate in micro-edm using dimensional analysis. The model developed is based on thermo-physical properties of inconel 600 alloy material such as electrical conductivity, thermal conductivity, density, specific heat, and melting point. For this study, four effective parameters namely voltage, capacitance, edm feed-rate, and pulse on-time are varied and drilled micro holes using tungsten carbide tool electrode. The adequacy of model is verified by finding the mean error, root mean square error and average error. The predictability of the model with experimental results is observed more than 94% using dimensional analysis. © 2022, the author(s), under exclusive license to springer nature singapore pte ltd.
