Question

Which of the following process is used for gear finishing?
1. Hobbing
2. Shaping
3. Milling
4. Shaving or burnishing

Answer 1

Correct Answer - Option 4 : Shaving or burnishing

Explanation:

Gear finishing processes:

1. Conventional finishing process for gears:
   1. Gear shaving
   2. Gear grinding
   3. Gear honing
   4. Gear lapping
   5. Gear burnishing
   6. Gear skiving
2. Advanced finishing processes for gears:
   1. Gear finishing by electrochemical honing.
   2. Gear finishing by electrochemical grinding.
   3. Gear finishing by abrasive flow finishing (AFF).

Gear hobbing:

• It is the process of generating gear teeth by means of a rotating cutter referred to as a “hob”
• Hobbing can be used to produce spur, Helical, & worm gears, as well as splines in almost all material (ferrous and non-ferrous metals & plastics), but not bevel or internal gears.
