Question

What is the reason for using unconventional or advanced machining processes? high strength alloys all of these high accuracy and surface finish complex surfaces?

Answer 1

Those are the options in the question:

A. Complex Surfaces
B. High Accuracy and Surface Finish
C. High Strenght Alloys.
D. All of the Above

The answer to this question is ALL OF THE ABOVE. OPTION D.




An unconventional machining process (or non-conventional machining process) is a unique kind of machining process in which there is no immediate contact between the instrument and the workpiece.

There is a requirement for machine instruments and procedures which can precisely and effortlessly machine the hardest to-machine materials and workpieces with multifaceted and exact shapes in the progressed machining process.

Answer 2

Unconventional or advanced machining processes are used in order to able to drive high steel alloys, to construct complex processes and to achieve high accuracy and surface finish. 
Therefore all the above mention options are correct. 
These allow the processes to be undertaken quickly and much more effectively. 
These processes are further classified into four types namely chemical processes, electro chemical process, electro thermal processes and mechanical processes.
