Question

What is the limit of surface area that is to be machined using USM?

(a) <100 mm^2

(b) <500 mm^2

(c) <1000 mm^2

(d) <1500 mm^2

I have been asked this question in class test.

This is a very interesting question from USM topic in portion Mechanical Processes of Advanced Machining

Answer 1

The correct option is (c) <1000 mm^2

The explanation: If the surface area to be machined is above 1000 mm^2, this type of machining will not be apt for the parts.
