a) (i) What are the advantages of laser beam machining in respect of the following:
Material removal mechanism, energy source, Energy transfer media, potential, current, power, gap and applications.
(ii) What is high energy rate forming? Discuss the theory of high energy metal forming. What are the advantages and limitations of high velocity forming?
b) With the help of sketches, show the degrees of freedom, a work-piece in space, possesses and how nine degrees of these freedoms can be restricted with the help of 6 pins. How are the remaining three degrees of freedom restricted when holding the work-piece for machining?
