A CNC router, short for Computer Numerical Control router, is a computer-controlled cutting machine used for cutting various hard materials, such as wood, composites, plastics, and non-ferrous metals. It is a highly versatile piece of equipment widely employed in woodworking, sign-making, prototyping, and manufacturing.
Key Components & Functionality:
· Controller & Software: The process begins with a digital design created in CAD (Computer-Aided Design) software. This design is then translated into a set of instructions (G-code)
by CAM (Computer-Aided Manufacturing) software. The controller interprets this code and directs the machine's movements.
· Gantry System: The router typically features a rigid gantry structure that moves the cutting tool (spindle) precisely along the X, Y, and Z axes.
·Spindle: This is the motor that rotates the cutting tool (router bits) at high speeds. Spindle power (measured in kW or HP) determines the machine's ability to cut through different materials and at varying speeds.
· Work Bed / Table: This is the surface where the material is fixed in place, often using clamps, a vacuum table, or T-slots, to prevent movement during the cutting process.
