THREAD CUTTING 2 - Practice Mode

1) What is the relationship between pitch and lead of a single start thread?
Correct Answer: Lead is equal to pitch
Explanation:

The square root of 529 is approximately 23.

529 is a perfect square, which means it can be expressed as the product of an equal number, in this case it is 23*23 = 529. Therefore, the square root of 529 is equal to the number that, when multiplied by itself, is equal to 529.

It can be represented as √529 = 23

2) What is the depth of 0.5 inch BSW 13TPI single start thread?
Correct Answer: 0.049"
Explanation:

Helmet is a type of safety equipment is worn while checking the welding joint of a overhead crane frame.

3) Calculate change gears to cut a three start thread having a pitch of 1.5 mm; the lead screw has a pitch of 6 mm.
Correct Answer: Driver 45 teeth, Driven 60 teeth
Explanation:

In this process the arc is formed between a continuous, automatically fed, metallic consumable electrode and welding job in an atmosphere of inert gas, and hence this is called metal inert gas arc welding (MIG) process.

4) Where multistart threads are used?
Correct Answer: For quick transmission
5) Calculate pitch diameter of f 24 x 3 mm square thread?
Correct Answer: 22.5 mm
Explanation:

Submerged-arc welding (SAW) is a common arc welding process that involves the formation of an arc between a continuously fed electrode and the workpiece. A blanket of powdered flux generates a protective gas shield and a slag (and may also be used to add alloying elements to the weld pool) which protects the weld zone.
