Question

Which machining processes are used for gear manufacture? 1.Form milling 2. Broaching 3.Roll forming 4. Hobbing Select the correct answer using the code given below: a) 1, 2 and 3 b) 1, 3 and 4 c) 1, 2 and 4 d) 2, 3 and 4

Answer 1

The machining processes that are used for gear manufacture are:

(c) 1, 2 and 4

1- Form milling is a very important gear manufacturing process.

2- Broaching is also a process that is used to manufacture the gears.

3- Roll forming is a process of bending metal strips etc and hence it cannot be used for the manufacturing of gears.

4- Gears can also be manufactured by the process of Hobbing.
