CNC machining is demonstrating how a new generation of computer programmers and design engineers has transformed the practice of machining into a precision art. There might be fine conventional machining techniques available today, but many manufacturers now opt for CNC machining because of the many advantages that its process has to offer.
CNC Machining Has Been Around For Decades
Numerical control machining has been around for decades already, with its theory first developed in the late 1940s by the United States Air force mechanics. From here, MIT engineers took the idea to the next level. The whole concept of using computers to run machines like grinders, routers, mills and lathes was one outstanding process from the beginning, as it allowed companies to make complex cuts with utmost accuracy. In fact, 1955 report stated that CNC machining “can reduce costs, reduce lead times, improve quality, reduce tooling and increase productivity.”
CNC Machining Has Many Advantages
These advantages becomes truer now than as ever, as we are seeing advances in computer technology continuing to revolutionize the CNC process. Some of the ways that CNC machining will help to give manufacturing businesses the edge include the following.
• They are programmed with a design that can be reproduced exactly. This is important in modern industry where a faulty cut on one component can render the whole machine unusable. These machines can control exact velocity and positioning, with usually an accuracy rate of 100%.
• They can produce thousands of identical parts in a relatively short amount of time, much faster than conventional machining.
• They can continuously be operated, 24 hours a day, seven days a week, and will only require a short down time for maintenance.
• They can easily be updated by changing the software, and can be reprogrammed in a short span of time. This allows them to quickly shirt from making one part to another. Also, they can store past programs that can be pulled out and used at any time.
• A visual test of every new program allows designers to ensure that the desired effect is achieved.
• Advanced software allows CNC machines to make products that cannot be made by hand, even by the most skilled machinists available.
• Because the machine does the skilled work, the machine operator does not need to have advanced training. Most CNC machine operation can be learned by virtual training. Once the first part has been inspected, the succeeding parts will only need minimal inspection.
• They only require to be supervised by one worker. Once they are programmed, they can usually work by themselves. They will reduce workload as well as the human error incidence. This will also help increase plant safety, as workers are not using dangerous tools.
• They come with automated cooling systems, protecting the equipment from heat damage. They may incorporate chip storage and conveyor belt waste removal.
• They can be used to make both plastic and metal parts.
