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 exhibit the following behaviour:
1
increases linearly
2
decreases linearly
3
does not change
4
first increases and then decreases
