(a) “As the etching rate increases, low surface roughness values occur.”

(b) True

(c) False

I had been asked this question in my homework.

This interesting question is from CHM topic in portion Chemical Processes of Advanced Machining

Answer 1

Right answer is (a) “As the etching rate increases, low surface roughness values occur.”

Easiest explanation: High etching rates result in low surface roughness values.
