CNC Prototyping and Its Advantages
CNC (computer numerical control) prototyping is a fairly new process in the field of machining that allows for better efficiency through higher levels of automation, and by making the machine and its computer controls carry out 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 can be left to itself for hours or even days if needed, allowing operators to perform other tasks. This also allows a company to employ fewer operators, therefore saving on overhead expenses. Without an operator, safety is increased as no one will be holding the tool, and in the event of a potentially hazardous machining error, only the tool will suffer damage. CNC prototyping machines can also work a lot faster than human machinists, as they are much stronger and have no need to take breaks. They can also be operated late at night, when most of the workers would have gone home, since machines do not need to be bothered about being sleepy or getting paid for overtime.
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 slight variations among finished results, while a CNC machine will come up with exactly the same result each time. This is highly important in the modern time of homogeneous and exchangeable parts, where a single defective cut can render the machine entirely unusable. All that will be necessary is one program to be developed and installed into the machine. Then the machine can toil away at however many work pieces are needed, producing an exact replica down to thousandths of an inch each and every time.
The third considerable advantage to CNC prototyping is the machine’s flexibility. 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 large advantage over other machines, as they are quick to shift to producing an entirely different output without needing new part installations or an overhaul of key components. This also guarantees that CNC prototyping machines can meet growing customer demands, considering they can easily shift from producing parts in surplus to parts that are lacking if necessary.
