What is CNC Turning
In CNC turning, a chuck (or specialized clamp) holds bars of material and, as they are rotated, a tool is fed to the piece to remove material to create a specific shape. A turret, which holds a group of tools, is programmed to move along the work piece in three different axes of motion to shape the material according to the assigned specifications.
Since CNC turning involves removing material from a work piece, it`s considered a [subtraction machining" process. It is done on a lathe machine, which can be used on all types of material, from wood to metal to plastic. It can also be done on a mill or a drill press.
Turning is primarily used to create cylindrical parts. It can be completed on the outside or the inside of a work piece, which is known as boring. The process can also be used to conduct various other operations, including:
· Grooving: Cuts grooves or creates narrow cavities in work pieces.
· Taper turning: Creates a gradually decreasing diameter in a cylindrical shape.
· Drilling: Produces round holes, which are typically for screws and bolts.
· Facing: Cuts a flat surface perpendicular to the axes of the milling cutter.
· Parting: Separates one part of the work piece from another.
· Knurling: Creates vertical, horizontal or crossing lines on the work piece.
· Threading: Makes grooves that can be screwed into other objects.

Suitable Materials for Turning
In turning, the raw form of the material is a piece of stock from which the workpieces are cut. This stock is available in a variety of shapes such as solid cylindrical bars and hollow tubes. Custom extrusions or existing parts such as castings or forgings are also sometimes used.
Turning can be performed on a variety of materials, including most metals and plastics. Common materials that are used in turning include the following:
l Aluminum
l Brass
l Magnesium
l Nickel
l Steel
l Thermoset plastics
l Titanium
l Zinc
When selecting a material, several factors must be considered, including the cost, strength, resistance to wear, and machinability. The machinability of a material is difficult to quantify, but can be following characteristics:
l Results in a good surface finish
l Promotes long tool life
l Requires low force and power to turn
l Provides easy collection of chips
