Question

In AJM, surface roughness value will vary between which values?

(a) 0.01 – 0.10 µm

(b) 0.15 – 1.5 µm

(c) 2.0 – 5.0 µm

(d) 7.0 – 10.0 µm

I got this question in an interview for job.

This is a very interesting question from AJM in section Mechanical Processes of Advanced Machining

Answer 1

Right option is (b) 0.15 – 1.5 µm

For explanation: Surface roughness value in AJM varies between 0.15 – 1.5 µm, depending on grain size.
