CNC turning has been around for many decades, and the benefits over human controlled machines are vast. The first obvious benefit of using a CNC machine as opposed to a hand operated machine is the improved automation. Automation means the quicker production of CNC parts, and the elimination of human error. CNC turning machines can run unattended during their entire cycles, allowing for less human presence on the factory floor. When a machine is capable of working by itself, its operator will only need to be on standby in case something goes wrong, allowing him to use his valuable time doing other tasks.
Reduced operator fatigue is therefore one of the major advantages of CNC machines, and with no mistakes, and consistency in the workpieces produced, it is easy to see why human controlled machines are used less and less in industry. Of course, a CNC operator is required to program the machine, and this is a very skilled job that only highly trained engineers can do. However, the skill required to programme and oversee the running of a machine does not require the same mental concentration that is required for a machining expert to machine a piece by hand.
Modern CNC turning centres use machines that are so accurate and consistent in their work that they can boast an accuracy that is unbelievably high. By repeating its actions, a CNC turning machine can simple make hundreds of identical parts in just one hour. Once the CNC machine in question has been suitably programmed, it can simply be left to run by itself, producing thousands of identical parts, working until a human intervenes and swaps the program or turns off the machine.
Modern CNC machines can of course be programmed to produce not just one specific precision part, but many different parts. The program can be switched over quickly and with easy, the programmer simply switching the task of the machine in question. All the programmes are stored within the computer, meaning that they can be recalled at the touch of a button and that change-overs are quick and efficient. One machine is capable of making hundreds of different parts, and of these different precision parts, one machine can make hundreds and thousands every single day.
The benefits of CNC in industry are therefore very easy to understand. With the capability to make hundreds of parts every hour, the cost of parts to the consumer is reduced. Whereas in olden times a part would be turned by hand and would be costly to the consumer, now CNC precision parts are affordable and of a higher quality. Industries would literally stop at a standstill of it wasn’t for CNC machines and turning centres. The modern day factory floor will have many different CNC turning and milling machines, all working at the same time to make an impressively fast production line that will seldom fail or break down. With so little human intervention necessary, factory floors are efficient and produce hundreds and thousands of the highest quality CNC parts every single day.
