The recent development of new and advanced materials has led to industry experiments, innovation, and patents. As a result, various alloys were developed and implanted for multiple applications in the space, automobile, chemical, steel, and manufacturing industries. Cobalt- and nickel-based alloys have been designed to cater to high-temperature and oxidation-resistance alloys.
Here, various literature reviews are investigated, and the machining of Haynes-25 is done using an electrical discharge machine with an optimization technique of the L27 orthogonal selection of Taguchi. The controllable input procedure constraints are Pulse On time (Ton), Duty factor (Df), Current (I), Gap voltage (Vg), and Flushing pressure (Fp).
The performance characteristics output parameters considered are material removal rate, tool wear rate, and surface roughness values (Ra). Moreover, confirmation tests are conducted to determine the percentage error of the predicted model.
The confirmation tests and results showed that the duty factor and current greatly influence the M.R.R, E.W.R, and Ra machining performance. The optimized condition is obtained at the implementation of the confirmation test and using the level of significance, i.e., A3B2C3D3E3, which can be used for the patent with the value of M.R.R..R as 0.05702, E.W.R. of 0.0091, and Ra of 2.34. Furthermore, regression models are developed to predict the material removal rate, tool wear rate, and surface roughness.
It is suggested that industries use these optimum conditions to lessen unused material and raise the productivity of Haynes-25 Electrical Discharge Machining, which can be patented.
