Question

What is the value of specific energy used in Plasma beam machining process?

(a) 100 W/(cm^3-min)

(b) 200 W/(cm^3-min)

(c) 300 W/(cm^3-min)

(d) 400 W/(cm^3-min)

This question was addressed to me at a job interview.

I'd like to ask this question from Plasma Beam Machining-Introduction And Machining system in portion Thermal Processes of Advanced Machining

Answer 1

Correct choice is (a) 100 W/(cm^3-min)

For explanation: The value of the specific energy used in Plasma beam machining process is about 100 W/(cm^3-min).
