Effect of Process Parameters on Cutting Rate in WEDM of Incoloy 825

“…The conclusion was that the discharge current, pulse duration, dielectric flow rate and the interaction between discharge current and pulse duration were more significant parameters for cutting operation. [4] Tosun&Cogun in 2003 in their investigation on AISI 4140 steel using regression analysis concluded that the wire wear ratio increases with increase in pulse duration and open circuit voltage while decreases with increase in wire speed and dielectric fluid pressure. [5] Singh &Gargin 2009 investigated the effect of various process parameters of WEDM like pulse-ontime, pulse-off-time, servo voltage, peak current, wire feed, and wire tension on hot die steel using one variable at a time approach.…”

Computational Approach for Multi Performances Optimization of EDM

“…Traditionally, machining parameters are selected manually based on the engineer and operator experiences [3]. The selection of parameters in order to obtain the optimum machining performances is very complex due to the best parameter combination is unknown especially to the beginners and non machining expertise.…”

Multiobjective Optimization for Wire Edm of Wc-Co Composite Using Gra With Entropy Measurement

“…J.T. Huang et al [11] performed optimization of machining parameters of wire EDM based on grey relational and statistical analysis. An improved percentage of 11.69% for machining performances was obtained by applying the proposed approach.…”
