9.A] What is taper turning? Explain the taper turning operation by swiveling the compound rest method.
Answer:-
Taper Turning
Taper turning is an operation to produce a conical surface on the workpiece.
This can be machined by either workpiece inclined to the axis of the lathe or a tool moving inclined to the axis of the lathe.
Taper Turning by Swiveling the compound Tool Rest
- The workpieces which require a steep taper for short lengths the taper turning was done by swiveling the compound rest method.
- In this method, the compound tool rest is swiveled to the required taper angle and then locked in the angular position.
- For taper turning the compound, rest is moved linearly at an angle so that the cutting tool produces the tapered surface on the work piece.
- This method is limited to short taper lengths due to the limited movement of the compound tool rest.
