Solution:

Cutters with teeth on one or both sides, as well as on their periphery, are known as which of the following?

Side and face cutters

Slitting saws

Angle milling cutter

Solution:

Which of the following is true in case of “too quick” forming (too few passes)?

It makes the tooling and the process uneconomical

It makes process easier

It distorts the product

Eliminate the need of a skilled operator

Solution:

What is the correct condition for the second type of lever?

The effort is in between the fulcrum and the load

The fulcrum is in between the load and the effort

The load is in between the fulcrum and the effort

There are no such conditions for the second type of lever

Solution:

An orthogonal turning operation is being carried out under the following conditions: The velocity of the tool relative to the workpiece is 3 m/s, the feed is 0.5 mm, and the chip thickness is 0.6 mm. Find the velocity of the chip relative to the tool in m/s.

Solution:

In a turning operation, the tool life of the carbide tool was found to be 30 minutes at a cutting speed of 120 m/min, and 120 minutes at a cutting speed of 80 m/min. Calculate the tool life of the tool under the same conditions but at a cutting speed of 100 m/min.
