A variety of other machining operations can be performed on a lathe in addition to turning; these include the following:
The tool is fed radially into the rotating work on one end to create a flat surface on the end
Taper turning is a cylindrical turning procedure in which the diameter to be generated is constantly changing. This method is used to produce conical shafts.
Instead of feeding the tool along a straight line parallel to the axis of rotation as in turning, the tool follows a contour that is other than straight, thus creating a contoured form in the turned part.
In this operation, sometimes called forming, the tool has a shape that is imparted to the work by plunging the tool radially into the work.
The cutting edge of the tool is used to cut an angle on the corner of the cylinder, forming what is called a "chamfer."
The tool is fed radially into the rotating work at some location along its length to cut off the end of the part. This operation is sometimes referred to as parting.
A pointed tool is fed linearly across the outside surface of the rotating work part in a direction parallel to the axis of rotation at a large effective feed rate, thus creating threads in the cylinder.
A single-point tool is fed linearly, parallel to the axis of rotation, on the inside diameter of an existing hole in the part.
Drilling can be performed on a lathe by feeding the drill into the rotating work along its axis. Reaming can be performed in a similar way.
This is not a machining operation because it does not involve cutting of material. Instead, it is a metal forming operation used to produce a regular crosshatched pattern on the work surface.
