Manufacuring Processes An electro chemical machining (ECM) operation is employed too cut a square hole in a copper plate of 18 mm thickness. The dimensions of the hole is 20 mm on each side, however, the electrode dimension shall be slightly less than 20 mm to allow for overcut, and its shape includes a hole in its center to permit the flow of electrolyte and reduce the area of cut. The frontal area of electrode is 180 mm2. The specific removal rate for copper is C = 7.35 x 10-2 mm3/A-s. The applied current is 950 A. At 90 % efficiency, determine the time required to cut a hole of required dimensions.

A selection between advanced machining operation and conventional machine operation is to be made for mass production of 1000 parts. The part is a 20mm thick stainless steel plate and a hole of 10mm must be drilled. Calculate time required, material removal rate and feed rate for both processes to make a known decision to save production cost. The ECM process require 1000amp current with an expected efficiency of 90% whereas the conventional drilling is to be done with 8mm drill through hole. The point angle is 118°. The cutting speed is 15m/min and the feed is 0.30 mm/rev. The part handling time for ECM is 1min whereas for conventional process is 1.5min with the use of jig.
