A taper is generally turned in a lathe by feeding the tool
at an angle to the axis of rotation of the work piece. The angle formed by the
path of the tool with the axis of the work piece should correspond to the half
taper angle. A taper can be turned by anyone of the following methods:
1.
By Swivelling the Compound Rest.
2.
By Setting Over the Tailstock Centre.
3.
By a Broad Nose form Tool.
4.
