What is the value of gap maintained between the electrodes when we use servo mechanism?
(a) 10 – 100 µm
(b) 100 – 200 µm
(c) 200 – 500 µm
(d) 500 – 1000 µm
I have been asked this question in final exam.
My doubt is from EDM-Mechanism of Material Removal topic in portion Thermal Processes of Advanced Machining
