A router machine, also known as a CNC router or computer numerical control router, is a type of machine used for cutting and shaping various materials, such as wood, plastic, and metal. The machine is controlled by a computer and uses a rotating cutting tool, called a router bit, to carve out the desired shape or design.

CNC router machines consist of a cutting bed, a gantry system that moves the cutting tool in different directions, and a computer controller that directs the movement of the cutting tool. The machine reads digital instructions from a computer-aided design (CAD) software and translates them into precise movements of the cutting tool.

Router machines are used in a wide range of industries, including woodworking, metalworking, and prototyping. They are often used to create complex shapes and designs that would be difficult or impossible to achieve with traditional cutting tools.

Router machines can also be used to perform other operations, such as drilling, boring, and carving, by changing the type of cutting tool used. They offer high precision and repeatability, making them a popular tool for both small-scale and large-scale manufacturing operations.
