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.
