Problem 1. (Electrochemical Machining)
An ECM operation is used to cut a hole into a plate of stainless steel that is 10 mm thick. The hole has a
rectangular cross section, 15 mm by 25 mm. The operation is accomplished at a current = 1300 amps.
Efficiency is 97%. Determine the feed rate and time to cut through the plate. The specific removal rate C
for stainless steel = 2.46 x 10-² mm³/A-s.
Problem 2. (Electric Discharge Machining)
Iron is to be machined in an EDM operation. If discharge current = 30 amps, what is the expected metal-
removal rate? The melting point of iron is known to be 1539°C, and the metal removal rate constant of
proportionality K = 664 in Sl units (5.08 in U.S. customary units)
