.... Design/methodology/approach One factor at a time (OFAT) approach has been used to perform the experiments. Pulse on time, pulse off time, peak current and servo voltage were chosen as input process parameters. Cutting speed, material removal rate and surface roughness (Ra) were selected as output...

... (from 0 to 28.5 kA.m^-1), the cutting speed (from 6 to 136 m.min^-1), the advance speed and the cut depth (pass). Both of the previous parameters are fixed respectively at 0.125 mm.rev^-1 and 0.5 mm. The material being cut is made of XC38 steel. The tool wear is evaluated...
