A compound gear has a stud that carries how many gears?

Solution:

What is a mortise gauge?

A striking tool

A marking tool

A boring tool

A planning tool

Solution:

In which type of machining operation, the motion of the cutting tool is both rotary and translating?

Turning

Milling

Planing

Drilling

Solution:

Which of the following is not a component of an Ultrasonic Machining (USM) system?

Lead screw

Concentrator

Transducer

Slurry delivery

Solution:

The angle between the rake face and a plane perpendicular to the rake face is known as the

Side rake angle

Side relief angle

End relief angle

Back rake angle

Solution:

The time taken to drill a hole through a 30 mm thick plate with the drill rotating at 300 rpm and moving at a feed rate of 0.25 mm/revolution is:

10 sec

17 sec

12 sec

24 sec

Solution:

For a given operation, the cutting speed is 60 m/min, the exponent is 0.27, and the constant is 78. Determine the tool life in minutes.

16.2 minutes

2.6 minutes

5 minutes

1.78 minutes

Solution:

In orthogonal machining, the cut chip thickness is greater than the uncut chip thickness. The primary reason for this is:

Thermal expansion

Friction between tool and chip interface

Bond between consecutive shear planes

None of the above

Solution:

Jigs are provided with some tolerance, which is dependent on the tolerance of the job. Consider the following:

A = Tolerance on Jig

B = Tolerance on Job

What is the approximate relation between A and B?

A = 0.2 × B

A = 0.05 × B

A = 0.1 × B

A = B

Solution:

A turning tool with a sharp corner and a major cutting edge angle of 50° is being used at a feed of 0.05 mm. Another cutting tool has a nose radius of 1.8 mm and a feed of 0.268 mm. The minor cutting edge angle of the turning tool for the same surface roughness of the two tools will be (in degrees).

13.68°

6.46°

11.15°

8.14°
