Question

Rotary swaging process is also called as incremental forming or oscillating forming process.

(a) True

(b) False

The question was posed to me during a job interview.

My enquiry is from Swaging in section Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer 1

Correct choice is (a) True

The best I can explain: Rotary swaging is basically an incremental forming process which is also called as oscillating forming, because it takes place in many small processing steps. One of the benefits of the incremental forming process compared to the continuous processes is the homogenous forming of the material. High forming ratios can also be achieved by a rotary swaging process in a single processing step.
