MT UNIT I MECHANICS OF CHIP FORMATION

   1. The point at which the cutting tool reaches, beyond which it will not function satisfactorily until it is reground, is called as

• Tool wear

• Tool failure

• Tool diffusion

• None of the above

2. Which cutting condition affects the cutting temperature predominantly?

• depth of cut

• cutting speed

• feed

• none of the above has any effect on cutting temperature

3. The cutting tool removes the metal from workpiece in the form of

• solid blocks

• powder

• chips

• all of the above

4. Which type of chips form while machining of brittle materials?

• continuous chips

• discontinuous chips

• Built-up chips

• all of the above with some proportion

5. The angle between side cutting edge and end cutting edge is called as

• approach angle

• nose angle

• side relief angle

• end relief angle
