Advanced and complex materials machining are the biggest problem in present industries. Advanced and complex materials used in different application like super alloys, tool, steels, ceramics, and composites with the need of high accuracy and good surface finishing. Its material very harder, so material removal is very harsh. This challenge can be solved by unconventional machining processes. The unconventional machining machine is machining the material to achieve high accuracy, reduce the material removal time and respectable surface finishing on the surface of the material. Wire cut electrical discharge machining (WEDM) is less used in turning operation in now a day. So, in this research, design and develop a new turning WEDM machine. In developed turning WEDM, different parameters effect on machining on turning operations. So, some parameters are investigated in this research. Experiments investigate the effect of varying peak current, infeed and revolution per minute of spindle on GCr15 material to examine the influence on the material removal rate (MRR) using ANOVA analysis. In the experiment, L27 orthogonal array is chosen for full factorial design of experiment (DOE) to manner analysis. The ANOVA calculation by both mathematical steps and design expert software. The Experimental outcome shows that the maximum material removal rate is 4.2 mm3/min at 90µm rotational infeed.
