CNC Machine: Introduction, Types and Applications

CNC Machine: Introduction, Types and Applications

CNC machine is a high-precision computer control manufacturing technique that has developed over the years as technology and computers have improved. The Milling machine was invented by John T. Parsons (1913-2007), the father of the second industrial revolution. Manufacturing will be dominated by the connection of machines with computers in the future, he realizes. 

An electromechanical device called a CNC machine, or Computer Numerically Controlled device, is an electro-mechanical device that manipulates tools around a varying number of controls, usually three or five, and with high precision. Engineers and makers use CNC machining to create physical parts from computer files, while 3D printing known as additive manufacturing can be used to generate physical parts.

A CNC machining process involves removing material from a stalk using a subtractive process. Digital instructions known as G-Code are used in these machines. As a result, a digital design can be transformed into a physical part faster and with higher precision.

Types Of Software Used In CNC Machines

CAD (Computer Aided Drawing)

Designs are created using these software programs. There are three types of CAD programs: AutoCAD, Rhino3D, and SolidWorks. It is also possible to use CAD solutions that are hosted in the cloud.

CAM (Computer-Aided Manufacturing)

Before the machine does any real cutting, CAM allows users to set up a “job tree” to organize workflow, specify tool trajectories, and run cutting simulations. CAM applications are CAD software add-ons that create g-code, which informs CNC tools and moving parts where to go.

Types of CNC Machine

CNC machine tools cut or move material as programmed on the controller, the type of cutting can vary from plasma cutting to milling, laser cutting, routing, and lathes.

Below are the types of Milling machines:

  • Lathes: The lathe is used to make symmetrical objects, such as cones, spheres, and cylinders. A spindle rotates the material against a grinding or carving tool that makes the desired shape.
  • Drills: Drills work by spinning a drill bit and moving a bit into contact with a stationary stalk.
  • Milling: it involves the use of a rotary cutting tool to remove material from a stock piece. In a CNC machine, the CNC moves high-accuracy ball screws to the exact coordinates programmed.

Plasma cutter: CNC plasma cutter uses a powerful laser to cut.

Applications of CNC Machine

Following are the applications of the CNC Machine: 

  • Dental equipment particularly dental crowning
  • Used by the defense ministry to make weapons and firearms
  • In the construction industry to achieve the amount of precision required
  • Aviation, automotive, and railway industries use CNC
  • In research and development, it helps to develop accurate prototypes
  • On a CNC machine, practically anything that has to be created in the proper quantities of almost any material may be done.

The CNC machining is made up of a small computer into which the program is input to cut the metal according to the instructions or specifications. The computer comprehends exactly what has to be accomplished and does all of the cutting operations. The Shaping machine functions like a large computer that must be programmed and follows all of your directions.

Working Principles Of CNC Machine

With a CNC machine, the program is fed into a minicomputer, which cuts the metal according to instructions. Computers handle all cutting processes. Milling machines function as vast computers that receive programs and follow instructions.

Lathes, milling machines, drilling machines, and other tools can be used to run CNC machines. By removing some metal, the object is given the right shape and size.
