Analysis of the sensitivity of the parameters affecting the rate of removal, surface roughness and width in the wire electrical discharge machining

The sensitivity analysis shows that pulse duration parameters, wire speed, and discharge flow are most effective parameters for cutting rate, and pulse duration parameters, dielectric rate, and discharge flow are most effective parameters for surface roughness, as well as pulse duration, wire speed, and discharge current for gap width. Pulse duration with 72%, wire speed with 14%, and discharge current with 10% has the greatest impact on the chip removal rate.
