there are five basic taper turning methods. taper turning by form tool.
taper turning by setting over the tailstock.
taper turning by swivelling the compound rest.
taper turning by taper attachment.
taper turning by combining feeds.
An operation performed on a lathe that feeds a tool at an angle to the length of the workpiece in order to create a conical shape.
A = Large end diameter of the taper B = Small end diameter of the taper L = Direct distance between A and B Formula: A \ B \ L \ 2 then Invert Tangent = The degrees you set your tool post at.
Taper problems on a lathe can be caused by many things. Below are the most likely possible causes and solutions:Misaligned tail stock- In most cases the tail stock can be realigned with its setting screws- Worn tail stock slides - Send for repairMisaligned Head stock- The head stock can be re-alignedMisaligned bed- The entire machine should be leveled againWorn bed ways- The machine should be sent for regrinding the beds

The function of the hand wheels on a lathe are to move the various carriages and the quill of a lathe by hand to its required positions.Most lathes have four hand wheels.Carriage hand wheel - For moving the saddleCross slide had wheel - For transverse movement of the tool postCompound had wheel - For moving the compound slide that can be set to an angle for taper cuttingTail stock hand wheel - To move the quill forward and backward for centering or drillingHand wheels on a lathe are connected to a screw which accommodates a nut that is attached to the above-mentioned components thus enabling movement when turned by hand.
