Advantages of CNC Prototyping

CNC (computer numerical control) prototyping is a comparatively new process in the machining world that allows for greater efficiency through higher levels of automation, and by having the machine and its computer controls perform all the work. While CNC prototyping machines are complicated and pricey, they almost instantly pay for themselves by decreasing the workload and controlling errors.

The first main advantage of CNC prototyping is that it improves automation, removing the need of an operator for all but a few parts of the work. CNC prototyping machines may be left alone for hours or even days, allowing operators to do other tasks. This also allows a company to employ fewer operators, therefore saving on overhead expenses. Without an operator, safety is increased, because in case there is a jam or other potentially dangerous machining error, no one will be holding the tool and the damage will be confined to the tool itself. CNC prototyping machines can also work significantly faster than human machinists simply because they are stronger and need no breaks. They can also operate late at night, when most workers have returned home, because machines do not have to worry about getting sleep or receiving overtime pay.

The second most significant benefit to CNC prototyping is that it produces the same exact result each and every time. Even the best human operator will have trivial variations among finished outcomes, but a CNC machine will bring exactly the same result all the time. This is truly important in the modern era of uniform and transposable parts, where a single problematic cut can make the whole machine useless. All that is needed is a single program to be created and fed into the machine. Then the machine can work away at however many work pieces are needed, producing an exact replica down to thousandths of an inch each and every time.

The third substantial advantage to CNC prototyping is the flexibility offered by the machine. Though humans are a lot more flexible and trainable in comparison to machines, a CNC machine can be totally reprogrammed in a matter of hours to manufacture a completely different product. Therefore, it is possible to revert back to old programs or install new programs if a new work piece is needed. This gives CNC prototyping machines a huge advantage over other machines, being easy to shift to a totally different product output without requiring new parts to be installed or a overhaul of core components. This also makes sure that CNC prototyping machines can cope with customer demand, because they can readily shift from parts that are in surplus to parts that are lacking, in case a need arises.
