CNC Machining & Software

What is CNC programming?

CNC programming (Computer Numerical Control Programming) is utilized 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 CNC machine

    3-axis machining

    The most common CNC machines produced commercially. Used for simple prismatic parts—to complex molds, medical or aerospace parts.

  • 4 axis machining

    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 CNC machine

    5-axis machining

    Popular in parts where complex shapes and small clearances, are the norm—such as impellers, turbines, intake ports and more.

  • Lathe machine

    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.
