What is taper Describe the taper turning by swiveling the compound rest?
This method uses the principle of turning taper by rotating the workpiece on the lathe axis and feeding the tool at an angle to the axis of rotation of the workpiece. The tool is mounted on the compound rest which is attached to a circular base, graduated in degrees.
What is taper turning formula?
Taper Angle Calculation: D = large diameter, mm. d = small diameter, mm. L = length of taper, mm. tan α = BC / AD = D – d / 2L. D – d / L = K.
Which one of the following is the disadvantage of taper turning attachment?
Disadvantage is that there is only one angle value possible for the tool to be ground at a time.

How did the countershaft work on a Boxford Lathe?
The countershaft assembly – built as part of the lathe so making it a self-contained unit, ready to run – was carried neatly on two bars passing through bosses cast into the back of the headstock-end foot. Control was by a lever protruding through the foot’s front face, a “quick-thread” mechanism being provided to slacken and tighten the belt.
