Knowing About CNC Machining Service  

Computer Numerical Controlled (CNC) Machining is the best way to remove material via high-speed precision machines. Precision machines make use of a wide variety of cutting tools in order to create the final design. You can consult manufacturing companies in Australia for CNC Machining Service.

Most Common CNC machines are:

  •    Vertical milling machines
  •    Horizontal milling machines
  •    Lathes

You can manufacture complex cylindrical shapes in cost effective manner by using a CNC lathe or 3 or 5-axis CNC milling machine.  In CNC lathe machine the part stock turns automatically whereas the cutting tools remain stationary. If we talk about CNC mill, here the cutting tools move automatically but the stock remains fixed. Custom fabrication can also be done with the help of CNC machines.

For creating the geometry of a part below mentioned things are controlled by CNC computer

  •    The rotational speed and movement of the stock
  •    Feed rates of the stationary tools

In order to create square features the round geometry is firstly created on CNC lathe then square features on a CNC mill.

If you want to make a part on a CNC Machine, you have to feed programs in it. The feed program further instructs the machine how it should move.  The programme instructions that are given to the machine are encoded by software i.e. CAM (computer aided manufacturing). This is done in association with CAD (computer-aided design) model that is provided by the customer. You can click here to get more information related to CNC machine.

The CAD model provide by the customer is loaded into the CAM software and tool paths are made on basis of the required geometry of the manufactured part.  Once the tool paths are known the CAM software can easily create machine code. This code tells the machine following things:

  •    How fast to move?
  •    How fast to turn the stock or tool?
  •    Where to move in a 5-axis X, Y, Z, A, and B?
