A New Approach in Turning by Wire Electrical Discharge Machining to Evaluate the Effects of Machining Parameters on Material Removal Rate

The application of Wire Electrical Discharge Machining (WEDM) for machining of precise cylindrical forms on hard and difficult-to-machine materials is presented. At first, the design of a precise, flexible and corrosion-resistant rotary spindle submerged is introduced. The spindle has been mounted on a five-axis wire EDM machine to rotate the workpiece in order to generate free form cylindrical geometries. The material removal rate (MRR) is an important indicator of the efficiency and costeffectiveness of the process. Several experiments are conducted to consider effects of power, time off, voltage, servo, wire feed rate, wire tension, and rotational speed (factors) on the MRR (response). A L18 (21×37) Taguchi standard orthogonal array is chosen for the design of experiments. Analysis of variance (ANOVA) as well as regression analysis are performed on experimental data. S/N ratio analysis is employed to find the optimal condition.
