Parametric Optimization During Wire Electrical Discharge Machining using Response Surface Methodology

Optimization the machining parameters by using VIKOR and Entropy Weight method during EDM process of Al–18% SiCp Metal matrix composite

“…The quadratic model equation for the three input process parameter is written as x and 3 x respectively. The coefficients are found by an appropriate method such as the least square method or Minitab Software (Velmurugan et al, 2011;Shandilya et al, 2012) …”

“…Also the table shows the difference between the maximum and minimum level value and their ranking among the process parameter for this selective model. (Sahoo et al, 2013;Shandilya et al, 2012). For the conformity test the overall percentage of error with its experiments value and predicted values is evaluated by considering the Eq.…”

Comprehensive Analysis of Wire Electric Discharge Machining Process in Machining High Chromium High Carbon Steel

“…Pujari Srinivasa Rao et al [9], predicted the residual stress in machining Aluminium 2014 T 6 alloy as 8.2 to 405.6 MPa and proved that, there was no surface cracks formed in microstructure study while compared to other materials. Ravindranadh Bobbili et al [10] revealed that, the brass wire broke with the increased wear rate due to increase in input energy and depicted the formation of craters, debris and micro cracks. Zhe Chen et al [11] depicted that, the Inconel 718 had reduced fatigue life, when machined using wire and the cracks originated, from the already existing defects.…”

Optimization of Material Removal Rate of WEDM Process on Mild Steel Using Molybdenum Wire

“…Approximately 70% increase in productivity was reported by using coated electrode as compared to the uncoated electrode [24]. Various kind of design of experiment techniques such as full factorial design [19], Taguchi method [17,20] and RSM [22] was also used to design the optimum number of experiments. Also WEDM was performed in different mediums and a medium having oxygen mist dielectric was suggested to be better.…”
