Optimisation of machining parameters using grey relation analysis for EDM with impulse flushing
The present work demonstrates the optimisation process of multiple responses, i.e., material removal rate (MRR) and tool wear rate (TWR) of electrical discharge machining (EDM) by grey Taguchi analysis. The work piece material was AISI P20 tool steel and a cylindrical copper electrode was used with...
