CNC machines are into existence since the 1940s. Basically, Computer Numerical Control is a technology where the movements of machines are controlled by a computer. As this technology is faster and efficient, it is extremely used in the manufacturing industry. CNC machines form objects by cutting materials and producing fine shapes.
Today, CNC machining has become fully-integrated manufacturing technology because of CAD, advanced production capabilities and high speed automation. Some manufacturers build their own CNC machines while others depend on additional service providers for CNC equipment to ensure smooth integration.
Probing further, let us see how CNC technology has made a huge impact on the betterment of the manufacturing industry.
Speed – In the past, when there were no CNC machines, mills, drills, and routers were run by operators. They used to analyze and read a drawing to determine an ideal way to design essential features of different parts. In the case of a complicated part, it was reoriented and remounted by hands. To include orienting features and to maintain critical dimensions, engineers had to work hard. This task used to take a huge amount of time for designing and manufacturing.
Luckily, CNC machines came into existence and solved all the issues of engineers. Today, CNC technology is used to read 3D modelling Cad files, and computer plans the machining operations automatically. Moreover, automated CNCs of advance level have articulating tables and heads to reorient parts and tools without even unmounting a part. Instead of controlling everything manually, operators can make use of CNC machines to interpret CAD files.
Thus, because of computer automation and integration, intricate parts are made quickly.
Accuracy – CNC technology not only makes parts speedily but also provides high precision and accuracy. As parts don’t need to be remounted, and all the critical operations are carried out by a high-precision machine, the chance of errors reduces to a great extent. However, the accuracy of the first part that you have designed depends mostly on the accuracy of the CNC machine. And the precision from part to part depends on how each part is mounted in the machine.
The best thing about CNC technology is that less waste is produced and thus, production cost also gets reduced.
Scalability – CNC machines also provide the advantage of scalability over old and outdated machining. Some machines are so efficient that they can perform more than one operation at a time and can run continuously for 24 hours. If you are into the manufacturing industry, then by investing in a CNC machine, you can perform operations faster and can a huge quantity of similar products in a short time span.
Your ideas are turned into reality – The most significant impact of CNC machining on the manufacturing industry is that your idea can be turned into a product quickly. For this reason, the technology of CNC machine is best for prototyping and testing in the design process. Designers and technicians who come up with a new concept, mock it up in CAD and within few days have machined prototypes.
