“…It was found that discharge current and pulse interval are more influential on MRR and Surface roughness than open circuit voltage. Poros and Zoboruski [37] investigated volumetric efficiency in WEDM of Ti6Al4V taking into consideration both process parameters and material properties. A semi-empirical model was developed to examine variation of WEDM efficiency using different wire materials, different process parameters by applying dimensional analysis.…”

Titanium and its alloys have been experiencing extensive development over the past few decades stimulated by a series of their unique properties, i.e. high strength to weight ratio maintained at elevated temperature, high hot hardness, high fracture resistance, and exceptional resistance to corrosion at temperature below 500°C. Machining of titanium, however, is considered as cumbersome with the conventional manufacturing practices, and there is a critical need for developing and establishing cost-effective methods of machining. This research work is mainly focused on the effect of WEDM parameters, such as pulse on time, pulse off time, peak current, spark gap voltage, wire feed rate and wire tension has been varied to investigate their effect on material removal rate and overcut for pure titanium. The experiments are planned, conducted, and analyzed through response surface methodology. An attempt has also been made to construct a micro-model for prediction of material removal rate using dimensional analysis. The predictions from this model have been validated by conducting experiments.

a b s t r a c tIn the current investigation, a multi response optimization technique based on Taguchi method coupled with Grey relational analysis is planned for wire-EDM operations on ballistic grade aluminium alloy for armour applications. Experiments have been performed with four machining variables: pulse-on time, pulse-off time, peak current and spark voltage. Experimentation has been planned as per Taguchi technique. Three performance characteristics namely material removal rate (MRR), surface roughness (SR) and gap current (GC) have been chosen for this study. Results showed that pulse-on time, peak current and spark voltage were significant variables to Grey relational grade. Variation of performance measures with process variables was modelled by using response surface method. The confirmation tests have also been performed to validate the results obtained by Grey relational analysis and found that great improvement with 6% error is achieved.

“…Coated brass wire can also produce exceptional surface finish. Porous and Zaboruski [11] developed the model of efficiency of cutting by application of dimensional analysis. The developed semi-empirical model enables analysis of the influence of the most important process parameters and properties of machined materials on volumetric efficiency of cutting.…”
