A CNC machine, or Computer Numerical Control machine, is a type of manufacturing equipment that is operated by computers using pre-programmed software and codes to control machining tools. These machines automate the cutting, shaping, and fabrication of materials like metal or plastic with high precision and consistency, eliminating the need for manual control by an operator
. CNC machines work by executing sequences of commands written in specialized programming languages such as G-code and M-code. G-code directs the machine's movements-such as speed, position, and feed rate-while M-code controls auxiliary functions. The process typically starts with creating a computer- aided design (CAD) of the part, which is then converted into G-code. The CNC machine reads this code and performs the exact operations needed to produce the part
. Common types of CNC machines include mills, lathes, routers, grinders, lasers, and water jets, all used to manufacture parts and prototypes across various industries. These machines can perform complex tasks like cutting, drilling, tapping, and engraving with great accuracy and repeatability
. In summary, a CNC machine is a computer-controlled tool that automates manufacturing processes by precisely following programmed instructions to shape and create parts from raw materials.
