Before looking at CNC machines in detail, let’s take a step back: what is CNC work, what does CNC machining involve, and why has it become so fundamental for companies all over the world?
What CNC machining means
CNC stands for computer numerical control, and its main function lies in its meaning. CNC machines receive input from internal software, into which data on the type of production and machining, the number of components needed, the size and the material are entered. The software is programmed to carry out these “orders” given from outside and, once started, produces everything requested extremely quickly and precisely. Easy, fast, precise. Incredible, isn’t it? Of course, the sequence of instructions entered into the software must be just as precise. But don’t worry: there are very easy, intuitive programs to use, so you won’t have too much difficulty.
The first CNC machine
Although more and more machines now use CNC, the first real CNC dates back to the 1940s, for machining the camshaft of an aircraft engine (which could not be reached physically and therefore had to be monitored remotely).
The reason so much work is still done with CNC today is that this technology saves a great deal of time (and, why not, a lot of money too).
