Explanation:

Taper Turning by Swiveling the Compound Rest:

Taper turning by swiveling the compound rest is a machining process used to create tapered surfaces on a workpiece. The compound rest, which is part of the lathe, is swiveled to a specific angle relative to the lathe axis to achieve the desired taper.
In this method, the compound rest is set at an angle corresponding to the taper angle to be produced. As the tool moves along the compound rest, it cuts the workpiece to create a taper. The angle of the compound rest determines the taper angle of the workpiece.
Due to the limited travel of the compound rest, this method is only suitable for producing short tapers. The compound rest can only move a limited distance, restricting the length of the taper that can be produced. For longer tapers, other methods such as taper turning attachments or tailstock offset methods are more appropriate.

Limitations:

Limited to short tapers due to the constraints of compound rest travel.
Not suitable for high production efficiency as the setup and operation are relatively slow.
Surface finish may not be optimal compared to other taper turning methods.
