Electrochemical Machining has wide application in the specialized fields such as aerospace and defense industries. In this study Al7075 composite is considered as a workpiece material due its applica- tions in die and mould making industries. The effect of heated electrolyte on machining rate was studied. The electrolytes are heated with infra-red light source. The experiments were conducted with unheated sodium nitrate (NaNO3) and acidified sodium nitrate electro- lyte. Moreover the machinability of anisotropic proper- ty of Al7075 was studied by drilling blind holes on plain top surface (i.e. X - plan) and on the side surface (i.e. Y - plan). The surface topography was analyzed using Scanning Electron Microscope and the effect of the machining parameters on the depth of the blind hole and the respective surface quality were studied. Based on the experimental results, the infra-red light heated electrolyte with addition of concentrated H2SO4 shows better machining rate which is nearly two times than the electrolyte at room temperature. The machining rate is better for infra-red heated elec- trolyte compared to the electrolyte at room tempera- ture. Applied voltage, Duty cycle and electrolyte con- centration has a significant effect on the machining rate. The heated electrolyte improves the machining rate but decrease the quality of the blind hole. The anisotropic property has the notable effect on the ma- chining rate. The Y-direction plane shows good machinability compared to X-direction plane.
