CNC stands for Computer Numerical Control. CNC machining can be defined as a manufacturing process in which pre-programmed computer software is used to control the movement of factory tools and machinery. The process can be used to control a wide range of complex machinery, from die casting to plastic injection molding. With CNC machining, very complex cutting tasks can be accomplished in a single set of prompts.s

Before CNC machining was invented, all industrial metal fabrication processes were completed done with Numerical Controlled (NC) machines which had many challenges. Back then machines needed live operators to prompt and guide the commands of machining tools through buttons, levers, and wheels.

In addition, variables on the operation of CNC machines will vary from one CNC type to another. There are several different types of CNC machines available. Anything from laser cutting machines to metal machines, so the mechanics of each different machine will be different; however, the basics work primarily for all the different CNC machine types.

As for the benefits, the benefits of a CNC machine are the same for every machine as it is for every company that owns one. A CNC machine offers one big benefit to its owners in that intervention by the worker is needed less, as the machine does all of the work once the software is programmed to the desired specifications. The machine will continue to run until the process is complete, all completely unmanned. This frees up the worker to perform other tasks if need be.

Another advantage is, it improves safety, productivity, efficiency, and accuracy in industrial manufacturing processes.

With CNC machining operators can maximize the use of raw materials and minimize waste. A skilled engineer might be able to make the same components but when each component is thoroughly analyzed, most likely the components will be different. So, a company can increase profit through the optimal use of raw materials.

Another advantage is that once an engineer correctly programs the machines, they can continuously produce the same quality components in a shorter time. They can shorten production processes, so a company can produce more components and receive more orders.

However, despite the fact that CNC machining has a ton of advantage it does have a drawback in that it is very expensive to implement. It requires a hefty investment meaning it is only beneficial in the long run because it helps minimize production costs.

That said investing in CNC machining is highly recommended for companies to stay competitive and profitable.
