A workpiece is taper turned using lathe, where large diameter of workpiece is D and small diameter d. If the length of this workpiece is L, then half angle a is given by:
1
\(\rm \tan \alpha=\frac{(D-d)}{2L}\)
2
\(\rm \tan \alpha=\frac{(D-d)}{3L}\)
3
\(\rm \tan \alpha=\frac{(D-d)}{L}\)
4
\(\rm \tan \alpha=\frac{(D-d)}{4L}\)
