Question

The operating speed of thread rolling is much faster than that of thread cutting process.

(a) True

(b) False

This question was addressed to me during an online interview.

I want to ask this question from Thread Rolling in chapter Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer 1

The correct answer is (a) True

Explanation: In thread rolling process, the process is carried out at much faster rate than the thread cutting process. This basically reduces the machine cycle time. In this process, the blank is produced at the pitch diameter of the thread, but in cut threads the blank is prepared at the major diameter. So, more material is required during the process.
