Question

A device/mechanism used to position a work piece in the same position, cycle after the cycle is called

• A. Indexing device
• B. Guiding device
• C. Clamping device
• D. Locating device

Hint:

- Locating establishes the initial spatial orientation of the part. - Indexing shifts or repositions the part through precise, uniform steps or intervals across consecutive machining cycles.

Answer 1

The Correct Option is A

In repetitive production, a workpiece or a tool has to be brought back to the exact same station or angular position over and over so that every cycle produces an identical result. An indexing device is the mechanism built for exactly this job, it rotates or shifts the workpiece by a fixed amount and locks it there, so cycle after cycle the part always lands in the same repeatable position for the next operation. This is different from a locating device, which only fixes position for a single setup, or a clamping device, which simply holds the part still once it is positioned. Since the question is about repeating the same position again and again through many cycles, the mechanism being described is the indexing device.
