What is CNC programming?
CNC programming (Computer Numerical Control Programming) is used by manufacturers to create program instructions for computers to control a machine tool. CNC is highly involved in the manufacturing process and improves automation as well as flexibility.
Types of CNC machines
CNC programmers write instructions for CNC machines, where a computer is connected to the mill, along with electrical drives and sensors for a complete system. This computer controls the movement of the machine axis.
-
3-axis machining
The most common CNC machines produced commercially. Used for simple prismatic parts – to complex moulds, medical or aerospace parts.
-
4-axis simultaneous
This type of machining is necessary when part geometry wraps around a part, common in the aerospace and other industries.
-
5-axis machining
Popular in parts where complex shapes and small clearances are the norm – such as impellers, turbines, intake ports and more.
-
Lathe and mill turn
Lathes and mill turn machines are capable of turning a part and drilling, cutting or carving out the shape that is needed.
