Q. In an ultrasonic machining (USM) process, the material removal rate (MRR) is plotted as a function of the feed force of the USM tool. With increasing feed force, the MRR exhibits the following behavior:

Q. Ultrasonic machines used in the material removal process require ultrasonic transducers. The transducers work on different working principles. One of the working principles of such ultrasonic transducers is based on

Q. In ECM, the material removal rate will be higher for metal with

Q. During the electrochemical machining (ECM) of iron (Atomic weight = 56, valency = 2) at current of 1000 A with 90% current efficiency the material removal rate was observed to be 0.26 cc/s. If Titanium (atomic weight = 48, valency = 3) is machined by the ECM process at the current of 2000 A with 90% current efficiency, the expected material removal rate in gm/s will be

Q. While removing material from iron (atomic weight = 56, valency = 2 and density = 7.8 g/cc by electrochemical machining, a metal removal rate of 2 cc/min is desired. The current (in A) required for achieving this material removal rate is
