What You Should Know About CNC Machining

CNC stands for Computer Numerical Control. It refers to the act of manipulating traditional machines through computer systems. Since there is an increase in the usage of computers in the process of industrial manufacturing, CNC has become quite common. The operation of conventional industry equipment such as millers, centre lathes, drills, and routers happen via computers for achieving better control.

It may appear like a computer is trying to control everything, but CNC’s unique software is what differentiates it from other technologies in the market. You can locate CNC machining in numerous industries for aiding production since it streamlines the procedure of manufacturing products.

CNC Programming & How It Works

CNC Machining tends to rely majorly on its programming. The human programmer should input the correct codes and also make sure that they work well. You can’t expect to have CNC machining in the absence of codes. G-Code is the language that’s present behind CNC. The majority of manufacturing machines possess code for dictating 1-2 functions.

The G-Code tends to be more intricate than this. Also, the G-Code tends to control multiple varying behaviours within CNC machines. They consist of coordination, speed, and feed rate. Once you write and feed the G-Code to the CNC machine, the need for a human operator doesn’t come up. Why? Well, it’s because the code performs the majority of the work.

CNC Machines & Its Types

CNC Machines usually fall into either conventional machining technology or novel machining technology. You should always consider the specific needs of the project whenever you pick the CNC machine of your type for adding to your workshop.

Conventional Technologies

They include:

Milling Machines

This CNC machine is used by many companies today, making it a common pick. They consist of using rotary cutting tools for removing materials from their stock unit. Also, they can execute multiple functions such as drilling, cutting gears, producing slots, and boring in a specified material piece.


They function by choosing to spin the drill bit and also moving or shifting the bit into and about contact by using a stock material’s stationary block. The CNC drills assist in making precision holes wherever you require them.


They are the inverse of the drills. It spins the material block right against a drill bit. Lathes usually create contact towards the material by choosing to laterally move the cutting tool until it ends up touching the spinning material in a progressive manner. Lathes are mainly utilised with wood and metals, removing all the unnecessary excess material, leaving behind a useful component at all times.

Novel Technologies

Chemical or Electrical Machining

An array of novel technologies is utilising specialised techniques for cutting materials. Some examples consist of electron beam machining, photochemical machining, electrochemical machining, ultrasonic machining, and electrical discharge machining. The majority of these technologies tend to be increasingly specialised. Plus, they are utilised during special cases or occasions in mass production that involves a specific material type.

More Cutting Mediums

You will also come across many other novel technologies, which utilises varying mediums for cutting the materials. Certain examples consist of laser cutting machines, technologies of water-jet cutting, and machines that cut oxy-fuel and plasma. The popularity of these machines is increasing in a variety of industries as of recently. But these pieces of equipment are all still increasingly specialised.
