Performance Enhancement of Material Removal Rate by using Cryogenic Treatment on Zinc Coated Diffused Brass Wire in Wire-Cut EDM Process
The effect of cryogenic treatment of wire has been studied on material removal rate obtained by wire electrical discharge machining
(WEDM). Two different wires have been used under the same input parameters. One wire was cryogenically treated and the other was simple and
without any cryogenic treatment. AISI D3 die steel was used as work piece material. The performance of wires has been measured in terms of
obtained material removal rate. Optimum set of input parameters for maximum material removal rate has also been determined. It is found that the
cryogenically treated wire produces more material removal as compared to non-cryogenically treated wire for same material.
