drilling machines was studied [ 9 ].
A two-level three-factor full factorial design was used to identify the ideal operating parameters. The input parameters are drilling speed, recast layer thickness, and hole taper. In Inconel 718, drilling and shaping process made into a single progression with identical electrode found that shape accuracy is affected by relative tool wear [ 10 ]. MRR, relative tool wear, and surface reliability are the objective parameters. Discharge current and duration are the main influence factor on HAZ. Two dielectric mediums, oxygen
