Zirconium carbide is an extremely

……………. refractory ceramic material.

To choose a machining operation

for a component, depends upon:

In conventional machining

processes, High Cutting Speeds result in:

Non-conventional machining processes do

not need hard cutting tools because:

In conventional machining it is of

great importance to achieve:

Non-conventional machining techniques offer

alternative methods for machining parts of complex shapes.

Very hard materials require harder tools in

non-conventional processes.

Non-conventional

machining processes utilize only one form of energy in direct form.

The

mechanical energy form, could be utilized in:

Machining in inaccessible areas is usually a drawback for conventional machining processes.
