CNC technology, or Computer Numerical Control, is a method used in manufacturing to automate machine tools. It involves the use of computers to control the movement of machines, such as lathes, mills, and routers, allowing for precise and repeatable production of parts. This technology enhances efficiency and accuracy in creating complex shapes and designs. CNC machines operate based on programmed instructions, which are often created using CAD (Computer-Aided Design) software. The process begins with designing a part digitally, which is then translated into a set of commands that guide the machine's movements. This integration of design and manufacturing streamlines production and reduces human error.
