A lathe is capable of performing numerous machining operations to deliver parts with the desired features. Turning is a popular name for machining on a lathe. Nevertheless, turning is just one kind of lathe operation.
The variation of tool ends and a kinematic relation between the tool and workpiece results in different operations on a lathe. The most common lathe operations are turning, facing, grooving, parting, threading, drilling, boring, knurling, and tapping.
Turning is the most common lathe machining operation. During the turning process, a cutting tool removes material from the outer diameter of a rotating workpiece. The main objective of turning is to reduce the workpiece diameter to the desired dimension. There are two types of turning operations, rough and finish.
Rough turning operation aims to machine a piece to within a predefined thickness, by removing the maximum amount of material in the shortest possible time, disregarding the accuracy and surface finish. Finish turning produces a smooth surface finish and the workpiece with final accurate dimensions.

Different sections of the turned parts may have different outer dimensions. The transition between the surfaces with two different diameters can have several topological features, namely step, taper, chamfer, and contour. To produce these features, multiple passes at a small radial depth of cut may be necessary.
Like Jim said think the whole project through before you even chuck it up.
I was taught to plan my steps so as to get as much done with out removing the work from the chuck.
Check your stock first.Face and put a center in it then run it out past where you need it and move up the tail stock with a lubed dead center and spin it to check for out of round or bends. Make sure it's large enough to hold plus extra for cutting off.
If you have to remove it from the chuck mark the jaw on the work so you can put it back in the same place.
Once you are ready to machine stop and think it through again.
A 20 minute machine job can take 3 times as long to plan then to do.
If you run into a problem ask us. Take a picture as that will help us give you the right advice.
