What is a CNC Router?

A computer numerical control, or CNC, router is a computer-controlled cutting machine that is used for cutting a wide variety of hard materials, such as wood, composites, aluminum, steel, plastic, glass, and foams. The CNC router can perform the tasks of many carpentry machines, such as panel saws, spindle molders, and drilling machines. They also have the ability to cut grooves and mortises. On the other hand, this router is very similar to a CNC milling machine. Instead of manual routing, the tool paths are controlled by computer numerical control. The CNC router is one of many tools that have CNC variants.

Efficiency and CNC Router

A CNC router typically produces consistent, high-quality work and increases factory efficiency. Unlike a jig router, a CNC router can produce one-off production as effectively as repeated identical production. Its benefits include automation, precision, reduction of waste and errors, and time to market for the finished product.

CNC Router Usage

The human operator selects the machine tool (such as a 0.25-inch v-bit or a 0.75-inch core box bit), speed, cutting depth, and tool path. For the cutting path, most machines offer options for tracing vectors, cutting outside of vectors, or cutting inside of vectors. The operator determines the center point of the workpiece, secures the workpiece to the table, moves the bit directly over the marked center and onto the surface of the workpiece, and marks this as the starting point. The operator then moves the bit up a few inches and selects the operate G-code function. The machine design then begins cutting.
