Question

What is the value of surface roughness, when special conditions are applied?

(a) 0.001 – 0.025 µm

(b) 0.025 – 0.05 µm

(c) 0.05 – 0.075 µm

(d) 0.075 – 0.1 µm

I got this question at a job interview.

I'd like to ask this question from CHM topic in portion Chemical Processes of Advanced Machining

Answer 1

Correct answer is (b) 0.025 – 0.05 µm

To explain I would say: Surface roughness obtained when special conditions are applied, is between 0.025 – 0.05 µm.
