(a) “Using PCM, very high tempered materials are machined easily.”

(b) True

(c) False

I had been asked this question in an interview.

The above asked question is from PCM-Applications and Advantages topic in division Chemical Processes of Advanced Machining

Answer 1

The correct option is (a) “Using PCM, very high tempered materials are machined easily.”

The best I can explain: PCM can be favourable for very high tempered and brittle materials unlike that of traditional machining, where they tend to break easily.
