Abstract:

Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. The hard machine materials like high nickel, Cobalt, and titanium alloys can be machined by nonconventional machining. HC HCr dies steel is one of the hardest materials which are very difficult to machine using conventional machine tools because of its hardness values. Also, if used, the wear rate of the tool will be very high. Material removal is achieved by electrochemical dissolution of an anodically polarized workpiece, which is one part of an electrolytic cell in ECM. Hard metals can be shaped electrolytically by using ECM, and the rate of machining does not depend on their hardness. The tool electrode used in the process does not wear, and therefore soft metals can be used as tools to form shapes on harder workpieces, unlike conventional machining methods. The process is used to smooth surface, drill holes, form complex shapes, and remove fatigue cracks in steel structures. The Literature survey says that when velocity is directly proportional to MRR (Material Removal Rate). So we desired to improve the velocity of the electrolyte. The electrolytes pass through the tool holes. To enlarge the tool diameter 1 mm to 3 mm, finally, compare the experimental result of 1 mm and 3 mm diameter multi-jet tool. Which one are yield better MRR and Minimum surface roughness?
