“…The influence of discharge current, voltage, pulse on-time, pulse off-time, duty factor, and flushing pressure on performance measures has been extensively researched. According to leading researchers’ literature reports, pulse on-time [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ], pulse off-time [ 26 , 27 , 28 , 30 , 32 ], voltage [ 26 , 28 , 33 ], current [ 30 , 31 , 32 , 33 , 34 ], and liquid flushing pressure [ 33 , 35 ] are the critical processes parameters that merit further investigation. Along with process parameters, the critical responses of the process, such as MRR, TWR, machined surface quality, and drilled hole accuracy, are used to evaluate EDM performance.…”
